What is burnout, exactly?
Burn-out has a definition, which surprises people who assume it is a figure of speech. In the eleventh revision of the International Classification of Diseases, the World Health Organization describes it as a syndrome conceptualised as resulting from chronic workplace stress that has not been successfully managed.
It has three named dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy.
Two details matter. Burn-out is filed under factors influencing health status and contact with health services, not as a medical condition. And the WHO is explicit that it refers specifically to phenomena in the occupational context and should not be used to describe experiences in other areas of life. If the flatness covers your whole life rather than your job, burnout is not the right word for it.
What is depression, exactly?
Depression is a clinical condition with a pattern and a duration. The American Psychiatric Association describes it as a persistent low mood or loss of interest in activities previously enjoyed, present most of the day, nearly every day, for at least two weeks, together with changes in sleep, appetite, energy, concentration or sense of self-worth.
The part people miss in themselves is the loss of interest. Exhaustion is loud. Depression often goes quiet instead: the things that used to pull on you simply stop pulling. Weekends do not restore anything. Time off produces relief for a day and then the same flatness in a nicer location.
It is also common — the World Health Organization estimates around 5 percent of adults live with depression — and it does not require an explanation to be real.
How do you tell burnout and depression apart?
No test settles it, but four questions separate them in practice, and they are the ones a clinician will ask you first.
- Where does it live? Burnout is job-shaped. If you are cynical and depleted at work and recognisably yourself at a friend's kitchen table, that points at burnout. If the flatness is the same in both rooms, it does not.
- Does it lift? A real holiday, a change of team, or a fortnight of proper rest usually moves burnout. Depression is famously unmoved by a good week.
- What has happened to interest? Burnout tends to leave interest intact and remove the energy for it. Depression removes the interest itself, including in things that cost no effort at all.
- What has happened to self-worth? Burnout usually sounds like "this job is pointless". Depression more often sounds like "I am pointless". That shift is one of the clearest signals to take to a doctor.
Can you have both?
Yes, and this is the ordinary case rather than the exception. Chronic workplace stress and depression are not alternatives on a menu; long unmanaged stress is a plausible route into depression, and depression makes work harder in a way that produces more stress.
Which is why the diagnostic question matters less than most people think when they are deciding what to do tonight. If the picture has lasted more than two weeks and taken things from your life, it is worth an appointment whichever label eventually fits.
It also matters because the fixes differ. Burnout responds to changing something about the work: hours, scope, boundaries, a conversation with a manager, sometimes a different job. Depression usually needs more than a schedule change, and treating it as a work problem alone is how people lose a year.
Check in with yourself
Two free things on this site help you see which picture you are in. Both run in your browser, and neither stores or sends anything.
The PHQ-9 depression self-check is the questionnaire clinics use: nine questions about the last two weeks, a score out of 27, and the standard severity bands. It screens; it does not diagnose. It cannot tell burnout from depression on its own, but a score near or above the threshold clinicians follow up on is a strong argument for booking rather than pushing through another quarter.
The six-question inventory, "How far am I from feeling like myself?", asks what an ordinary good moment used to contain and how much of it is still here. It is a useful counterweight to a work-shaped explanation, because it shows plainly whether the losses stop at the office door.
DepreScan itself is a private check-in about how you have been feeling, sleeping, thinking, socialising and functioning lately, followed by a simple snapshot and small daily steps aimed at whichever part of your life has slipped furthest. It screens, it never diagnoses.
When should you talk to someone?
Book an appointment if it has lasted more than two weeks. NHS guidance is to see a GP if you have been feeling down for more than two weeks, and you do not have to decide which condition this is before you go — that is the appointment's job.
Go sooner if sleep or appetite has changed noticeably, if you have stopped doing things you used to need, if drinking has crept up, or if the language in your head has moved from "this job is pointless" to "I am pointless". If you are having thoughts of being better off dead, that is not something to schedule: call or text 988 in the US, call Samaritans on 116 123 in the UK and Ireland, or find your local line at findahelpline.com. If you might act on those thoughts, or someone is in immediate danger, call your local emergency number.
Bring specifics. "I've been exhausted and cynical about work for four months, I stopped seeing people in June, and the weekends don't fix it any more" tells a clinician more in one sentence than a label would.
Questions people ask
What is the difference between burnout and depression?
Burnout is tied to work. The World Health Organization defines burn-out as a syndrome resulting from chronic workplace stress that has not been successfully managed, with exhaustion, mental distance or cynicism about the job, and reduced professional efficacy — and says it should not be used to describe experiences outside the occupational context. Depression is a medical condition that persists across every part of life for at least two weeks and does not lift for a good weekend.
Is burnout a mental illness?
Not as classified. In ICD-11 the World Health Organization places burn-out in the chapter on factors influencing health status or contact with health services, and states explicitly that it is not classified as a medical condition. That is a statement about classification, not about severity — burnout can be seriously disabling, and it is a legitimate reason to see a doctor and to change something about the work.
Can burnout turn into depression?
They frequently occur together, and long unmanaged stress is a plausible route into depression, though a label is not what decides your next step. If the picture has lasted more than two weeks and has cost you sleep, people or things you used to enjoy, book an appointment regardless of which word fits. A clinician can separate them; the distinction is not one you have to make alone before going.
Will a holiday fix burnout?
It will tell you something either way. Burnout usually eases with genuine rest or a change in the work itself, so a real break that helps for more than a few days is informative. If two weeks off changes almost nothing, or the flatness is waiting for you on the first evening back, that points away from a work-only explanation and toward talking to a health professional.
