Yes I don't sleep a lot even when everything is fine and dandy, I get random unhelpful thoughts when I try, all of the negative things of course, when I've made an idiot of myself, when I've failed at something, said the wrong thing, done the wrong thing, you know. but it is exactly that. it's overthinking, because f you mention these things to other people involved in it they usually can't even remember it, so just try to get it in perspective, nothing is THAT important in the big scheme of things and try not to worry x
