Does anyone else have it related to absolutely NOTHING? I'm in the best job I've ever had, with an ethical and supportive company (something I've been desperate for for years), I'm finally finishing my degree, my wife is settling into her career, we're in the best financial position we've ever been by a significant margin, we're looking at new/bigger houses, everything on paper really couldn't be going much better... And yet I'm (just emerging from, thankfully) an extremely dark few months. Not my worst ever but definitely top 5.

My latest theory is that I have some sort of adjustment disorder... Any change (even 100% positive change) can send me into a bit of a spiral. My brain goes into overdrive trying to predict endless possible outcomes to endless possible situations and I end up mentally and physically exhausted.

I swear, I once had a (very brief) episode of derealisation (the world feels like "nothing is quite real") because we dramatically changed the colour scheme in the living room.
