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?
This is literally it and it's the worst thing to hear and build up because it sucks hard in the moment. It's essentially having to "grin and bear it" for a little bit. But this is the answer. This is something that I've learned and resisted against strongly during therapy, but when I finally found the strength to "grin and bear it," I was mad at myself for not doing it sooner because it really does become easier after the first few times.
It's okay if you feel like you can't because there'll come a day when you can, but if you can muster the strength, just do it. You'll thank yourself for that strength later on.
