Diagnosis & definition
Burnout vs. depression vs. exhaustion
They look alike from inside and need entirely different responses. Getting this wrong wastes years — and in one direction, it is dangerous.
These three get used interchangeably, and they should not be. They overlap, they can coexist, and they require different responses — in one case, urgently different.
I am a coach, not a clinician. Part of doing this responsibly is being clear about which of these belongs to me and which does not.
Exhaustion
What it is: a recovery debt. You have spent more than you replaced, and the mechanism still works.
How it behaves: rest converts. A long weekend of genuine sleep produces a genuinely better person. The improvement holds for a reasonable period.
What is intact: everything except energy. You still want things. You still find things funny. Good news still lands as good news. You are too tired to act tonight, and the wanting is unaffected.
What it needs: rest, and enough of it. Straightforward, and it works — which is the defining feature.
Burnout
What it is: a state in which the conversion from rest to energy has broken down, produced by sustained load without adequate recovery, usually over years.
How it behaves: rest stops working. Eight hours produces the effect of four. Two weeks away produces three days of benefit. The collapse rate is the marker — not how tired you feel, but how quickly recovery evaporates.
What changes: discretionary functions go first, in a consistent order — humour, patience, curiosity, generosity, spontaneity. Judgment degrades specifically: avoidance, premature closure, narrowed options, threat-weighting. Creative work stops before execution does.
The critical feature: it is largely situational. It lifts with distance from the environment, and it returns on contact with it. People with burnout are frequently fine on holiday and depleted three days after returning. That pattern is close to diagnostic.
What it needs: stabilisation first, then structural change to the arrangement producing it. Rest alone is necessary and not sufficient.
Depression
What it is: a clinical condition. Not a more severe burnout, and not something you arrive at by working too hard, although exhaustion and burnout can precede or accompany it.
How it behaves: it is pervasive rather than situational. It does not lift meaningfully with distance from work. Holidays do not help. The good days are not good.
What to look for:
- Flatness that does not respond to anything, including things that used to reliably work
- Early morning waking, or sleeping far more than usual
- Significant appetite or weight change
- Worthlessness or guilt out of proportion to circumstances
- Loss of pleasure across everything, not selectively
- Any thoughts of not wanting to be here, or of self-harm
What it needs: a doctor. Promptly. Not a coach, not a programme, not a retreat.
Why the confusion is dangerous in one direction
Mistaking burnout for exhaustion costs you time. You take a holiday, it does not hold, you lose another eighteen months. Bad, recoverable.
Mistaking depression for burnout is a different order of error. It delays treatment for a condition that responds well to treatment and worsens without it. And "burnout" is the more socially acceptable word — it sounds like a consequence of ambition rather than an illness — which means people reach for it precisely when they should not.
If you are reading this and quietly wondering whether the second one applies to you, that wondering is itself worth acting on. Call your doctor rather than another coach.
They can coexist
This is not tidy. Long-running burnout is a risk factor for depression. Depression makes ordinary load unmanageable and produces something that looks like burnout. Plenty of people have both.
Where that is the case, treatment comes first and coaching sits alongside it, not instead of it. I work alongside clients' therapists where it is useful. What I will not do is let a coaching engagement quietly drift into treatment it was never designed to be — that helps nobody and can do real harm.
A rough sequence
- Rule out the physical. Thyroid, iron, ferritin, B12, vitamin D, sleep apnoea. Unrefreshing sleep has real medical causes and several of them are common in exactly this population.
- Test whether it is situational. Does it lift with genuine distance from work, and return on contact? That points at burnout.
- Test whether it is pervasive. Does anything at all still land — a good meal, your children, music, a particular person? If nothing does, that points at depression.
- Test the conversion. Does rest still work? If yes, exhaustion. If no, something more.
None of this is a diagnosis. It is a way of deciding who to call.
Being precise here is not pedantry. These three need different things, and the cost of treating one as another ranges from a wasted year to a genuinely serious delay.
