You sound like a more sever case of me. On the tests I am borderline, not clinically an aspy but, I have anxiety issues that stem from abuse. I can handle social gatherings now, even enjoy one now and then but, at 20 there was no way in Hades I could even go to a social gathering - doing so resulted in a panic attack at the least and, a flashback with me going unconscious at the worst.
Back then, if I made a friend at all it was either someone a lot younger whom I knew I could keep in control, or someone a lot older that had the knowledge and patience to deal with my B.S. Now I can fake it pretty well. I do public demos in BDSM dungeons, karaoke at clubs, best this or that body part contests and such without panic attacks.
I do have one major trigger left that will send me into a nasty flashback. I can control it with a partner I trust, but even that is a major fight and I will be in panic attack mode but, if my partner is really into that, I'll go with it occasionally to please them. (yeah that trigger is sexual in nature).
I'm a firm believer that our mind is our most powerful tool, and can be our worst enemy if we let it get away with that crap. Except is the most severe cases, our mind can do more for us that nay medication or any other tricks we might try. If we make up our mind that we are going to beat a personal obstacle or demon, we can do it, and we don't need all of the drugs mainstream medicine will try to throw at us long term. Yes medication can be helpful short term for the really tough issues, but long term we can manage it on our own. Took me until I was 40 to get off all meds, but I did it and, now I have casual friends that have no idea I have any issues at all. Usually, I even shock partners when I have to tell them about my one remaining trigger before we get to having sex. I get a "You were, are, I mean - NO WAY, you seem too together." reaction and, that's a really good feeling
