I was really angry when I found out that most people aren't being constantly mentally bombarded by a highlight reel of all of the fuckups they've ever done, all the time
I was even angrier when their solution for me was 'Just don't let it bother you'
Improv and theater helped me. Being able to roll with the situation and turn it into something fun or different has saved me from constant anxiety. I also channeled that Simpsons energy of Homer's First Day so when I fuck up I expect jeers and taunts, which I can handle, instead of outright anger. And being able to roll the taunt back into a burn or accept it as valid criticism helps drop the subject.
Oh hey it's my experiences when trying to deal with people! Except it's like the first half goes well then I just must be doing something because I leave thinking things went well then find out later no
No they did not
And I pull my hair because it's usually something small and I'm just "why didn't you say shit at the time???" and I'm told that's rude but I was taught it's ruder to let shit fester??
This was so incredibly true when I was a kid. Really tough childhood. Didn’t help that one if my parents was authoritarian and prevented us from watching TV, further isolating us from those common social interactions of knowing TV shows or lines. Blocking TV was, of course, punishment for poor grades and failure to accomplish tasks at home too, because wouldn’t you know it, ADHD goes hand in hand with ASD.
I always had a hard time telling if people were trying to talk to me, which is especially frustrating because you can't safely err on either side. You always respond back, lots of intensely awkward and humiliating interactions with people having to explain they weren't talking to you. You stay quiet and wait for a clearer signal, some people will get offended and angry because they think you're purposely ignoring and insulting them somehow.
I wouldn't say that I get traumatised by social interactions going wrong but they definitely get stuck in my head for a while; I keep thinking about what I could have done differently, even if it wasn't really my fault.
