For me, in addition to all those other things, it’s that even most “good” companies are abusive, so there’s no escape. It’s just “how much abuse are you willing to put up with to work here?”, rather than “this place isn’t abusive”, and I can’t do that roulette anymore.
I’m taking some time off to reassess everything. Maybe in 6 months of absolutely minimal living (to coast on savings) I’ll feel better about it, but with the way things are racing downhill and picking up speed, I’m not optimistic.
