Yep. An entire childhood of my dad always calling me a spazz, my mom abusing me, kids in school avoiding me because I was weird, always feeling like the only person not in on the joke in college, getting cussed out and -- in one case -- physically assaulted in the workforce... I started devoting most of my energy to just reacting and hiding. I spent most days just getting to the end of all the social bullshit and obligations.
Whatever you do, don't tell me to relax. Every time I relax, everybody hates it. I suspect there's a good, interesting person with the capacity to be happy in here somewhere but I get so little time to actually be them.
This is the premise of American Psycho and it's a critique on a society that produces these traits in individuals. You didn't evolve to produce endlessly so that a tiny fraction of society can benefit at the expense of the majority. So you adapt instead.
I know that feel all too fucking well. My first meltdown was after a few drinks with my gf and I just started crying while looking in the mirror. She wasn't any help, insisting that the things I was speaking out loud to myself weren't true, one of the things being that I am "a farce that everybody believes in out of politeness".
