This is me since... at least high school. Probably earlier, but my memories are spotty. Almost all the things you mention present, often acutely, in relation to anything that is "to be done" - be it work or personal. Anything can trigger it, the moment it stops being something I do on a whim, and becomes something that I plan or is expected of me. No underlying medical condition to attribute it to. What to do then?

Have you already been to a psychiatrist? That sounds like it could be knock-on effects of growing up with untreated ADHD.

[TeMPOraL]

Yes. Treated for depression in my early 20s, but it only reduced those issues a tiny bit. Diagnosed with ADHD in my 30s (thanks to many comments like yours over the years on HN, which eventually made me talk with a doctor again); treatment was much more effective for the symptoms in question, but they never completely went away, and occasionally come back to bite with vengeance. I currently consider the effect of that treatment to be somewhere between "close, but no cigar", "you're holding it wrong" and "lulled into false sense of security".

One thing I observe being unstated for many mental health conditions is that the duration is often life.

Or that without fundamentally changing the set and setting of one's life, one can expect, on average, approximately the same metrics now as tomorrow, and so on and so forth.

Therapy and medication help, for some people, some of the time.
