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?
Cultivate an aura of mystery. Make cryptic pronouncements. Wear a lot of black and imply furtively that you might be some kind of wizard.
With that out of the way, you can now explain all your social missteps as the work of unruly spirits that haunt your every step, barely contained by your constant etheric battle (this is why you get tired and irritable after 15 minutes of uninterrupted conversation).
This has worked for me for at least a decade. It also helps if you work with computers, since about 80% of the time you'll either be a) talking to equally socially busted people or b) able to safely change the subject at any time by relating any of your completely inscrutable work gripes to people with sensible jobs.
EDIT: Also, not for nothing, tarot is actually a really pleasant systematic way to think about your life and your problems in a way that's outside your body but still informed by your thoughts and feelings.
