Like I just can’t think around them because the sounds they make and the things they talk about drive me up the wall.
Might be misophonia if it's all about the sounds.
If you're still seeing a therapist talk to them about what sets you on edge, and ask if you can try Beta Blockers to see if that helps you tolerate crowds or just interacting with people.
They'll block you're adrenal system, and all types of shit that pissed you off just won't be a big deal anymore.
It shouldn't be hard to try them out for general anxiety, and if it works you'll notice it immediately but takes a couple weeks to ramp up due to long halflife.
