Burnout or depression? Understanding exhaustion when you're still functioning
Still functioning does not rule out depression or make exhaustion unimportant. Burnout refers specifically to work-related exhaustion, distance from work and reduced effectiveness; depression can overlap with it. Understanding what has changed, what continuing costs you, and what helps you recover is more useful than choosing a label from an online checklist.
The work gets finished. You answer people. Then an ordinary evening feels beyond you: a conversation, making dinner, deciding what to do with the time that is supposedly yours.
Burnout sounds plausible because work has been relentless. Depression sounds too severe because you are still doing your job. High sensitivity might explain the overload, but why have things become harder now?
The useful question is not only “What can I still do?” It is also “What does doing it leave me able to do afterwards?”
Can you be depressed or burnt out and still function?
Keeping up with work does not rule out depression. Clinical evaluation considers symptoms and their impact across your life, rather than checking only whether you remain employed. Depression can involve persistent low mood or loss of interest, fatigue, sleep changes, hopelessness and difficulty thinking. Major depression typically involves symptoms lasting at least two weeks; duration alone does not establish a diagnosis. NIMH's overview explains the fuller picture.
You might be protecting the most visible part of life while everything less visible becomes smaller. Saying “I'm meeting deadlines, but I cancel everything afterwards” gives a professional something important to explore. It does not, by itself, identify a condition.
What is the difference between stress, burnout and depression?
These concepts overlap. This table explains the terms; it cannot tell you which applies to you.
| Term | What it describes | What the label alone cannot tell you |
|---|---|---|
| Chronic stress | A continuing response to sustained pressures, potentially affecting sleep, concentration, mood and physical wellbeing. | Whether another mental or physical health difficulty is also present. |
| Occupational burnout | WHO's work-specific phenomenon: exhaustion, distance or cynicism towards work, and reduced professional efficacy. | Whether depression coexists, or what care an individual needs. |
| Depression | A clinical condition involving persistent low mood or loss of interest or pleasure, with other symptoms and effects on daily life. | A single cause, or whether changes in circumstances are also needed. |
Stress can come from employment, caregiving, relationships or several directions at once. WHO's stress guidance describes its effects on health.
In formal ICD-11 usage, burnout is specifically occupational and is not classified as a medical condition. WHO's definition does not cover every form of prolonged exhaustion. Everyday language is broader: a carer may describe being burnt out, and their exhaustion still deserves attention.
Can work or a holiday tell you which it is?
Work can be central to your distress without ruling out depression. Research has found substantial overlap between burnout and depressive symptoms, alongside some differences. It cautions against neat internet distinctions. Bianchi and colleagues, 2020; comparative study, 2023.
Feeling better away from work, or enjoying a good afternoon, does not reliably exclude depression. Exhaustion beyond work does not establish it either.
A holiday changes several things at once: demands, routine, sleep opportunities and environment. Improvement gives information about what makes life more manageable. A lack of improvement calls for exploration; it does not prove a particular diagnosis or a permanently dysregulated nervous system.
Describe what changed: more energy, less dread, better sleep? What returned when ordinary demands resumed? Consider both your circumstances and your health.
Where do high sensitivity and autistic burnout fit?
If you identify as highly sensitive, sensory and social demands may matter. But a longstanding trait does not automatically explain a new loss of capacity.
Research on sensory processing sensitivity concerns responsiveness to environments, including supportive as well as adverse experiences. It does not establish “HSP burnout” as a separate diagnosis. Greven and colleagues, 2019.
Autistic burnout is a developing research concept describing exhaustion, reduced functioning and lower tolerance of sensory input in autistic people. Masking can contribute to the burden described. It extends beyond workplace exhaustion. Raymaker and colleagues, 2020. Later questionnaire research does not establish one universal treatment or rule out depression. Bougoure and colleagues, 2026.
Recognition in these descriptions does not establish autism. Read the fuller comparison of high sensitivity, autism and ADHD. This practice does not offer autism assessment or a specialist autistic burnout service.
What is useful to bring to a first conversation?
You do not need a polished explanation. These prompts can provide a starting point:
- What changed, and when? Include home and relationships, as well as work.
- What does continuing cost? What gets cancelled or left undone after the visible demands are met?
- What helps, even partly? Describe the circumstances, without trying to prove a diagnosis.
- What have you tried? Include previous therapy and practical changes.
- What would you like room for again? Choose something more specific than “back to normal.”
These are conversation prompts, not diagnostic criteria.
Persistent unexplained fatigue also deserves medical consideration. Sleep disorders, anaemia, thyroid problems, illness and medication effects can contribute. NHS guidance recommends medical review when unexplained tiredness persists or affects daily life. Psychological and physical contributors can coexist.
How can therapy help when you already understand the problem?
You may understand that you take on too much and still struggle to stop. You may know a limit is reasonable and still find setting it difficult. That gap is something to explore.
My position is that therapy should take both the demands and your response seriously. It cannot substitute for changes in unsustainable working conditions. Sensory demands need consideration too. Personal history may matter—for example, what being dependable means to you—but should not be imposed as the explanation for every exhausted person.
My approach is organised around Regulate → Integrate → Consolidate: developing ways to manage distress, exploring relevant experiences and patterns, and bringing that work into everyday decisions and relationships. These are guiding stages, not a fixed programme. Methods depend on what we understand together.

What would a first session involve?
A first session is a 50-minute conversation about what has been happening, what you have tried and what you want to be different. We begin exploring the difficulty and whether working together makes sense. It is a starting point, rather than a promise to settle a diagnosis in one meeting.
I work in English, German and Hebrew, in Vienna and online, where appropriate for your circumstances. You can bring the account of getting through the day with little left for yourself, without choosing the right label first.
This article cannot replace individual care. If you are having thoughts of harming yourself or suicide, seek prompt support from a local health professional. If you are in immediate danger or cannot keep yourself safe, seek local emergency help rather than waiting for an online appointment.
