Mental Health Vocabulary: 20 Words for Stress & Support

Mental health vocabulary helps people describe emotional experiences, discuss pressure at work or at home, and understand what support is available. These 20 terms explain stress, anxiety, mood, burnout, coping strategies, boundaries, rumination, social support, counselling and therapy using everyday examples without turning a word list into a diagnosis.

If you are searching for the difference between stress and burnout, the context matters. Stress can arise in many parts of life. The World Health Organization defines burnout in its ICD-11 classification as an occupational phenomenon associated with chronic workplace stress that has not been successfully managed; it is not classified there as a medical condition. Being tired after a busy day does not by itself establish burnout.

Quick answer: describe what you are experiencing, how long it has lasted and how it affects daily life. If distress is severe, persistent or worsening, seek advice from a qualified healthcare professional rather than relying on a glossary. If you or someone else is in immediate danger, use local emergency services or immediate crisis support. Words can help conversations, but they cannot determine what diagnosis or treatment a person needs.

What is mental health vocabulary?

Mental health vocabulary includes words for emotions, perceived demands, social support, coping and professional care. Some words are broad, such as wellbeing and mood. Others are used in specific frameworks: WHO’s burnout definition applies to the occupational context, and terms such as reasonable accommodation relate to workplace support that may be governed by local law. A clinician considers much more than a word in a message: symptoms, duration, context, functional impact and other possible causes. Avoid diagnosing yourself, a friend or a colleague based only on the terms listed here.

What to do first: a practical approach

For an ordinary non-emergency concern, a useful starting point is to observe and communicate without overstating certainty.

Notice what has changed: sleep, concentration, energy, mood, relationships or ability to complete familiar tasks.
Describe the situation in neutral language, such as “I am finding it difficult to concentrate after work,” rather than declaring an unconfirmed condition.
Identify immediate practical needs: adequate rest, a manageable workload, supportive company, a break or a timely healthcare appointment.
Talk with a trusted person or qualified professional. You may ask for privacy and explain whether you want advice, practical help or simply someone to listen.
At work, describe the specific task or schedule pressure and ask what organisational changes or reasonable adjustments might be available.
If symptoms seriously interfere with daily life, continue, worsen or create a safety concern, seek professional assessment promptly; emergencies require immediate help.

NIMH recommends paying attention to the duration and effect of distressing symptoms and seeking professional help when severe or persistent. WHO’s September 2026 mental-health-at-work factsheet stresses that workplaces have a responsibility to address hazards such as excessive workload, low control, bullying and discrimination. Self-care practices can support wellbeing, but they are not a substitute for addressing harmful conditions or obtaining appropriate treatment.

The full 20-word glossary with examples and distinctions

1. Mental health

Meaning: A person’s psychological, emotional and social wellbeing and capacity to function and relate to others. It is more than the absence of a formal mental disorder.

Everyday example: “I want to make time to discuss my mental health with a professional.”

Important distinction: Mental health is not identical to being cheerful every day.

Try this: Describe specific changes and strengths, not only a broad label.

2. Wellbeing

Meaning: A general sense of health, functioning and quality of life across relevant aspects of living. It can include connection, purpose, physical needs and emotional experiences.

Everyday example: “My wellbeing improved when the workload became more manageable.”

Important distinction: Wellbeing is not simply productivity or having no difficult feelings.

Try this: Identify the areas that affect your daily functioning.

3. Stress

Meaning: A response to demands, threats or pressures that a person perceives as challenging. Stress can be short-term or persistent and may have physical and emotional effects.

Everyday example: “I have been under stress because three deadlines overlap.”

Important distinction: Stress is not automatically an anxiety disorder or a sign of failure.

Try this: Name the specific demand and the effect it has on you.

4. Stressor

Meaning: An event, condition or demand contributing to stress. It could involve uncertainty, workload, conflict or another circumstance.

Everyday example: “Unclear instructions are a major stressor in this project.”

Important distinction: The stressor is the contributing circumstance; stress is the response.

Try this: Ask which part of the situation might be changed.

5. Anxiety

Meaning: A feeling of worry, apprehension or fear about possible threats or outcomes. It may arise in ordinary life and can also be a feature of clinical conditions.

Everyday example: “I have been feeling anxious before the meeting.”

Important distinction: Feeling anxious at times is not the same as receiving a diagnosis of an anxiety disorder.

Try this: Notice duration, intensity and impact, and seek assessment when appropriate.

6. Mood

Meaning: A person’s prevailing emotional state over a period. Mood can vary with experiences, health and circumstances.

Everyday example: “My mood has been low throughout the week.”

Important distinction: A low mood does not automatically establish depression or another disorder.

Try this: Report the pattern honestly rather than assigning yourself a diagnosis.

7. Burnout

Meaning: An occupational phenomenon involving chronic workplace stress that has not been successfully managed under WHO’s ICD-11 description. WHO describes exhaustion, increased mental distance or cynicism about one’s job and reduced professional efficacy.

Everyday example: “I am concerned that the prolonged workplace strain is affecting my health.”

Important distinction: Burnout is not classified by WHO as a medical condition and should not be applied indiscriminately to every life stressor.

Try this: Discuss work conditions and symptoms with an appropriate professional.

8. Exhaustion

Meaning: A state of intense tiredness or depleted energy. It can have physical, psychological and medical causes.

Everyday example: “The exhaustion has made routine activities difficult.”

Important distinction: Exhaustion alone does not identify its cause or prove burnout.

Try this: Seek medical advice for persistent, severe or unexplained symptoms.

9. Overload

Meaning: A situation in which demands exceed a person’s available time, resources or capacity. It can describe tasks, information or emotional demands.

Everyday example: “The team experienced overload when several urgent requests arrived together.”

Important distinction: Overload is a workload description, not a diagnosis of a mental disorder.

Try this: Identify what can be postponed, simplified or reassigned.

10. Coping strategy

Meaning: A method a person uses to manage an experience, demand or emotion. Strategies can be helpful, unhelpful or mixed depending on context.

Everyday example: “I use a short walk as one coping strategy after a difficult day.”

Important distinction: A coping strategy is not the same as treatment for a clinical condition.

Try this: Choose safe strategies and discuss concerns with a professional when needed.

11. Boundary

Meaning: A limit a person communicates about time, conduct, information or responsibility. Healthy boundaries may support respectful relationships and manageable work.

Everyday example: “I set a boundary about answering non-urgent work messages after my agreed hours.”

Important distinction: A boundary is not a licence to ignore agreed safety obligations or mistreat others.

Try this: State what you can do and what alternative arrangement is available.

12. Self-care

Meaning: Actions that help a person maintain or support their wellbeing. This can include rest, nutrition, connection and appropriate health care.

Everyday example: “Making a healthcare appointment is part of my self-care.”

Important distinction: Self-care does not solve workplace discrimination or replace professional care.

Try this: Choose practical steps without blaming yourself for systemic problems.

13. Resilience

Meaning: The capacity to adapt or recover when facing difficulty, with support and resources. It is not a demand that people endure any harmful situation indefinitely.

Everyday example: “Support from colleagues helped the team show resilience after the disruption.”

Important distinction: Resilience is not proof that exhaustion or mistreatment is acceptable.

Try this: Consider environmental changes and assistance as well as personal coping.

14. Mindfulness

Meaning: A practice involving attentive awareness of present experience, often without immediate judgement. It is used in different secular and therapeutic contexts.

Everyday example: “I tried a brief mindfulness practice to notice my breathing.”

Important distinction: Mindfulness is not suitable as the only response to every mental-health problem.

Try this: Choose approaches appropriate to your needs and preferences.

15. Rumination

Meaning: Repeatedly thinking about distressing experiences or worries without making helpful progress. It can feel like problem-solving while repeating the same upsetting loop.

Everyday example: “I noticed I was ruminating about the conversation all evening.”

Important distinction: Rumination is not identical to ordinary reflection that produces a decision.

Try this: Consider seeking support if repetitive thoughts become distressing or disruptive.

Meaning: Emotional, practical or informational help from other people and communities. Support can come from trusted friends, family, peers or organised services.

Everyday example: “I asked a trusted friend for social support while adjusting to the new role.”

Important distinction: Support is not always advice; listening and practical assistance can matter.

Try this: Tell the person what type of help would be useful.

17. Stigma

Meaning: Negative stereotyping, judgement or unfair treatment associated with a characteristic or condition. Mental-health stigma can discourage people from seeking assistance.

Everyday example: “The team discussed how to reduce stigma around mental-health support.”

Important distinction: Stigma is not the same as a clinically justified assessment of symptoms.

Try this: Use respectful language and avoid assumptions about capability.

18. Counselling

Meaning: A form of professional support involving discussion of emotional, personal or situational difficulties. Credentials, methods and regulation vary between countries.

Everyday example: “I asked whether confidential counselling was available through the service.”

Important distinction: Counselling and psychotherapy can overlap and are not always sharply separated.

Try this: Check the provider’s qualifications, approach and confidentiality terms.

19. Psychotherapy (talk therapy)

Meaning: A professional treatment approach that uses structured psychological methods and a therapeutic relationship. It may be offered in different formats and for different conditions.

Everyday example: “The clinician explained whether psychotherapy might be appropriate.”

Important distinction: Therapy is not identical to a casual conversation with a friend.

Try this: Discuss options, suitability and expected process with a qualified provider.

20. Reasonable accommodation

Meaning: An adjustment that supports a person’s ability to participate in work or another setting under relevant needs and laws. At work it may involve modified schedules, duties or access arrangements.

Everyday example: “The employee asked about a reasonable accommodation for medical appointments.”

Important distinction: An accommodation is not automatically available in the same form or under the same laws everywhere.

Try this: Ask for a private discussion of relevant needs and applicable procedures.

Worked example: talking about sustained work stress without self-diagnosing

Imagine a fictional employee who has been managing an excessive workload for several months. They feel tired after work, are finding it harder to focus and have started avoiding conversations about upcoming deadlines. They wonder whether to tell a manager, “I definitely have burnout.”

A more useful first description might be: “My current workload has increased significantly. I am exhausted most evenings and my concentration has been affected for several weeks. I would like to review the priorities and discuss what support is available.” This identifies the stressor, the experienced stress and the impact without asserting a diagnosis.

WHO distinguishes workplace burnout from ordinary distress in other areas of life. Its ICD-11 classification defines burnout as an occupational phenomenon, not a medical condition. It includes energy depletion, mental distance or cynicism toward work and reduced professional efficacy. That definition is helpful, but it does not establish the employee’s individual condition from a short account.

The manager’s response should not simply be “Try more mindfulness.” WHO’s mental-health-at-work factsheet discusses excessive workloads, long hours, low control and poor organisational support as risks. Appropriate workplace responses can include clearer priorities, reducing demands, improving schedules, preventing harassment and considering reasonable accommodations where applicable.

At the same time, the employee can ask for professional assessment if exhaustion, low mood or anxiety is persistent or significantly affecting everyday life. NIMH explains that severe or distressing symptoms lasting two weeks or more can warrant professional help and that a primary care provider can be a starting point. Urgent safety concerns must be handled more quickly.

Suppose a friend asks, “What can I do?” The employee could answer, “I would appreciate someone listening while I work out which deadlines are essential,” or “Could you help me find the appropriate employee support contact?” These are clear examples of social support.

Setting a boundary might mean asking for agreed response hours for non-urgent messages. It should be expressed respectfully and consistently with the person’s actual job requirements. Resilience should not be interpreted as silently enduring indefinite unreasonable demands.

If the employee notices repetitive worries at night, they might describe them as rumination rather than diagnosing an anxiety disorder from the pattern. A professional can help assess whether specific treatment or additional support is needed.

For coworkers or friends, avoiding stigma matters. Responding with “You are lazy,” “Everyone is tired,” or “Just be positive” can make a person less willing to ask for help. Better phrases include, “That sounds difficult; what has been happening?” and “Would practical help or professional support be useful?”

The vocabulary has done its job when it enables accurate communication about both personal experiences and working conditions, without confusing an ordinary word, a formal classification and a clinical diagnosis.

Common mistakes and better alternatives

Calling every difficult week burnout → use WHO’s specific occupational definition and avoid self-diagnosis.
Assuming a person who is coping well cannot need help → observe distress and functional impact rather than appearances.
Treating self-care as a replacement for reducing unsafe or unreasonable working conditions → address both systems and individual needs.
Assuming mindfulness is an appropriate treatment for every serious condition → ask qualified professionals about suitable care.
Using counselling, coaching and psychotherapy interchangeably without checking qualifications → confirm the service and scope.
Telling someone to “be resilient” as a way of dismissing harm → discuss workload, safety, support and realistic changes.
Waiting for a fixed two-week threshold during immediate danger → seek urgent or emergency help when safety requires it.

A fifteen-minute vocabulary exercise

Use fifteen minutes with an invented non-emergency situation. During the first five minutes, separate the words stressor, stress, exhaustion and burnout. Write which term refers to the demand, which refers to an experience and which has a specific occupational classification.

In the next five minutes, draft a respectful support request: “I am finding [specific task] difficult because [context]. Could we review priorities or identify appropriate help?” Do not describe a real person’s private health situation without permission.

For the last five minutes, practise a response to someone sharing a concern: “Thank you for telling me. Would you prefer that I listen, help with a practical task, or help you find professional support?” The aim is listening and clarity, not diagnosing or prescribing.

Real-world decision guide: deeper explanations

The twenty-word glossary gives the definitions. The following scenarios show how to distinguish related ideas when making real decisions or asking for help, while keeping the limits of a general reference clear.

Why naming a feeling is not the same as diagnosing a condition

Words such as stressed, anxious, low, exhausted or overwhelmed can help a person describe an experience, but they do not automatically establish a clinical disorder. The experience may have multiple contributing factors, including sleep disruption, illness, financial uncertainty, work demands or changes in relationships. A trained professional considers duration, intensity, functional impact and other health information. Rather than telling someone “You definitely have anxiety” after one conversation, it is more accurate to say “You seem worried; would you like to talk about what is happening?”

That approach also works when describing your own experience. You can say, “My concentration has been poor for several weeks, and I am struggling to finish normal tasks,” without assigning a label. A symptom description can help a healthcare provider decide what needs assessment. Avoid using internet checklists to rule out medical causes or to prescribe treatments. It can be useful to note when changes began, how often they occur, and whether daily activities or relationships are affected. If an experience becomes severe or raises safety concerns, contact an appropriate professional promptly.

How to distinguish a stressor from its effects

A stressor is something contributing to pressure, while stress refers to the person’s response to demands or perceived threats. An unclear deadline may be a stressor; persistent tension, difficulty sleeping and reduced concentration may be ways the person experiences stress. Treating these as different categories helps clarify what can change. If the problem is an impossible delivery schedule, simply telling someone to breathe more slowly will not remove the schedule. A useful response may involve renegotiating tasks, providing staff support or clarifying priorities.

Consider a fictional family whose childcare arrangements unexpectedly change. The stressor is the change in practical care and work availability. Family members may respond with worry, tiredness or frustration, but not in identical ways. A meaningful conversation could begin, “Which part of the situation can we solve this week?” followed by practical planning and support. If someone develops serious or persistent symptoms, a healthcare assessment may also be appropriate. Naming the stressor does not mean dismissing the person’s emotional experience or assuming the practical change is easy.

What a supportive workplace response to burnout looks like

The World Health Organization uses the term burnout for a workplace-specific occupational phenomenon associated with chronic stress that has not been successfully managed. It describes depletion or exhaustion, increasing distance or cynicism about work, and reduced professional efficacy. The term does not classify every tired employee as having a medical condition, and it cannot be established solely by counting overtime hours. Employers should examine how work is designed, whether demands are achievable and whether staff have adequate support and control, not only whether individuals practise self-care.

A fictional manager notices that a team is missing deadlines, regularly working late and reporting little control over conflicting tasks. A useful response might be to reduce unnecessary work, clarify decision rights, allocate resources and agree communication boundaries. Asking one employee to attend a wellbeing workshop does not by itself repair understaffing or harassment. The WHO’s September 2026 workplace fact sheet identifies excessive workload, low control and unsafe organisational conditions as potential risks. It recommends attention to organisational measures as well as individual support and management training.

How to ask for support without disclosing everything

People do not always want to share their complete personal history with a manager, colleague or relative. A practical request can describe a particular effect and the help sought: “I have been finding it difficult to concentrate in the morning. Could we discuss how to organise these tasks?” Another request might be “I have an appointment next week and need to review the schedule.” The right amount of information depends on the relationship, workplace rules, local law and what is needed to make an appropriate arrangement.

At the same time, someone may want to tell a healthcare professional more detailed symptoms in confidence. Prepare a factual summary of the onset, duration, severity and effect on ordinary activities, along with relevant medical information. If unsure about confidentiality, ask the provider what is recorded, who can access it and whether there are limits to confidentiality. Information-sharing rules vary by country and service. Avoid distributing another person’s health disclosures in an open group chat without their consent. Support should preserve dignity and allow the person to make informed choices.

Counselling, psychotherapy and ordinary conversation

Support can take several forms. A friend may listen and offer practical help; a counsellor may provide structured support in a professional relationship; a psychotherapist may use specific psychological methods as treatment. Professional titles, qualifications and the distinction between counselling and psychotherapy vary across countries. Some clinicians provide more than one type of service. The important questions are the provider’s actual qualifications, what the method involves, whether it suits the concern and how confidentiality and fees are handled.

Not every stressful situation calls for the same intervention. A short-lived scheduling problem may be addressed through practical changes, while persistent distress interfering with daily functioning can warrant assessment by a qualified professional. A person does not have to know which treatment they need before asking for help. A useful opening is, “I am worried about the way I have been feeling and would like an assessment of the options.” Avoid describing therapy as a quick guaranteed cure or suggesting that a friend’s advice replaces medically indicated care.

What boundaries can and cannot do

A boundary is a clear limit related to time, communication or respectful behaviour. At work, for example, someone might request that non-urgent messages be sent for the next working day rather than late at night, subject to agreed responsibilities. In a family, a boundary might mean not sharing a private conversation without permission. The goal is to make expectations explicit, not to control another person’s emotions or punish them. Good boundaries also consider the needs and duties that people have agreed to, including important safety obligations.

Boundaries alone cannot resolve every problem. An employee facing harassment may need formal safeguarding or complaints procedures rather than simply telling the harasser to stop. A caregiver may need external assistance when demands exceed what one person can reasonably do. When communicating a boundary, explain the situation and propose a workable alternative: “I can review that document tomorrow morning; for tonight’s emergency, please contact the designated on-call person.” The statement is specific, respectful and consistent with a shared process.

How to listen without adding stigma

When a friend or colleague says they are struggling, avoid assumptions based on outward performance. A person may still complete work or maintain social contact while experiencing significant distress. It is rarely helpful to respond with “You should be grateful,” “Everyone has it worse,” or “Stop thinking about it.” Such comments can prevent meaningful discussion. Instead, ask whether they would like listening, practical assistance or help contacting a professional service. Respect their choice, within the limits required by immediate safety concerns.

Stigma can also arise when people use mental-health labels as insults or treat one diagnosis as proof that a person is unreliable. Use person-centred, specific language and avoid sharing rumours. It is possible to acknowledge workplace performance concerns while supporting access to appropriate adjustments and fair processes. WHO highlights training, open communication and reducing discrimination as part of a healthier workplace. Compassion does not require pretending that serious problems do not exist; it requires discussing them without unjustified judgements.

When urgent support matters more than vocabulary

A glossary is useful for ordinary explanation, but it must not delay help during an emergency. If someone is in immediate danger, expresses an urgent intent to harm themselves or others, or is unable to remain safe, contact local emergency services or an appropriate crisis service immediately. If a person has alarming physical symptoms such as chest pain, breathing difficulty or a medical emergency, seek urgent medical care rather than assuming the cause is anxiety. The appropriate service depends on location and circumstances.

For significant but non-emergency distress, a primary care clinician, qualified mental-health professional or official local support service can help assess the next steps. NIMH advises seeking professional help when severe or distressing symptoms persist, especially if they interfere with normal activities. Its two-week discussion is guidance for noticing persistent symptoms, not a rule that a person must endure severe danger for a fixed number of days before seeking help. You can request support earlier whenever concerned.

How to separate individual self-care from organisational change

Self-care includes practical habits and appropriate health care that support wellbeing. For some people, adequate sleep, enjoyable activity, social connection or planned breaks may help. These practices should not be presented as an obligation to solve every structural problem. If a workplace has excessive workloads, unsafe conditions, bullying or persistent uncertainty, organisational action is also necessary. WHO’s mental-health-at-work guidance discusses both preventing workplace risks and helping individuals access support. The two levels should reinforce one another rather than replace one another.

A useful action plan can use two columns: changes the individual can safely make, and changes that require someone else’s cooperation or a formal system. For example, a worker might be able to schedule rest and ask for support, but only the employer can approve staffing, adjust unrealistic targets or investigate harassment. At home, a caregiver may seek a trusted support network and also need professional respite or community services. It is appropriate to ask, “Which part can I manage, and which part requires additional resources?”

Frequently asked questions

What are the most important mental health words to learn?

Start with mental health, wellbeing, stress, stressor, anxiety, mood, coping strategy, boundary, social support, burnout and professional care. The words support better conversations but cannot determine a diagnosis.

Is burnout a medical diagnosis?

WHO includes burnout in ICD-11 as an occupational phenomenon rather than a medical condition. Its definition refers specifically to unmanaged chronic workplace stress, not all forms of tiredness or life pressure.

What is the difference between stress and anxiety?

Stress is a response to perceived demands or pressures; anxiety involves worry or apprehension. They can overlap, and either may require assessment when distress is persistent or disruptive. The words alone do not diagnose a disorder.

When should someone seek professional mental-health support?

Seek professional assessment for severe, lasting, worsening or significantly impairing symptoms. NIMH highlights distressing symptoms that persist for two weeks or more as a reason to seek help, but urgent safety concerns should be addressed immediately.

Is self-care enough to treat a mental-health condition?

Not necessarily. Self-care can support wellbeing but cannot replace professional evaluation or treatment when indicated. At work, changes to harmful job conditions may also be necessary.
