Is this burnout, or was it undiagnosed ADHD the whole time?

I have both diagnoses, so here's the question that untangled it for me: does it have a childhood? Burnout has an on-ramp — you can usually point at the year things changed and the load that changed them. The ADHD side of my life had school reports from age nine saying the same things my manager was saying at 31. The other half of the answer is that they stack: masking ADHD in a job that doesn't suit you is expensive every single day, so a lot of people arrive at burnout precisely because of undiagnosed ADHD, and treating only the burnout leaves the engine running. None of that is a diagnosis and a checklist can't give you one either.

I self-diagnosed from short videos and spent about nine months and a fair amount of money on planners, timers and productivity systems, all of which worked for about a fortnight each. When I finally got in front of a psychiatrist it was depression sitting on top of burnout, and the thing that helped was neither a planner nor a stimulant. The cost of guessing wasn't just the money, it was the nine months I spent being annoyed at myself for failing at systems that were never aimed at my actual problem.

Gentle counterweight to the top answer. I was convinced I had ADHD for a year — every symptom list fit — and then I changed jobs and within four months the forgetfulness, the flatness and the inability to start had all gone and have never come back. Chronic stress does a very convincing impression of attention problems. Stay on the assessment list by all means, since fourteen months passes anyway, but change something about your load in the meantime rather than treating the wait as the plan.

It helped me to know they're not even the same category of thing. The WHO's ICD-11 lists burn-out as an occupational phenomenon and states explicitly that it is not classified as a medical condition, described in three dimensions: exhaustion, mental distance or cynicism about the job, and reduced effectiveness. ADHD is a clinical diagnosis with criteria and a clinician attached. So the honest version is that you can be fairly confident about the first from your own experience, and you cannot self-award the second no matter how many videos you watch.

Get on the list today. Change something at work this month. Don't wait for a label to give you permission to reduce the load.
