I know that here I am pretty loud and obnoxious, but IRL I actually have like, really bad social anxiety. Especially when talking to guys. (Actually come to think of it it's usually only happens when I have to talk to guys I find attractive 
)
Sometimes it's fine, but other times it's like my brain does a blue screen of death and I can't even think of words to say.
Is there a way to get my brain working normal in these situations? I already taken anti-anxiety meds and they help a little, but not always.
Any tips to stop my goofy ass brain from crashing?
Unfortunately for me I gave up trying to medicate my ADHD because while it did help, I got strong irritability from it, to the point where I was angry all the time and it was not fun for me or the people around me.
So I'm not the best person to talk to about ADHD medication. Other people here probably have better experiences.
Ah damn I'm sorry they didn't work for you! I was mostly just suggesting in case you hadn't tried since it seems to work so well but of course, mileage varies.
I think as others have said, body doubling and doing an activity together with someone can help a LOT, I know I'd rather play a board game/go to a movie/go on a walk or bike ride and so there's not pressure to talk the whole time.
Idk if having a fidget would help, but I have one of those fidget rings that I wear and it's pretty helpful for me/discreet
