Maybe this can help you a litte. Sometimes I toke. So as god or whoever wanted, a friend of mine passed out in front of me, while me being completely high. Right at the moment I was juts like "woaah dude, wtf. you alright" blablah the usual stuff, help him etc. But somehow this event burned into my head somewhere... in my concioussness. So every time I toked, I also had a panic attack. It was a feeling that I felt that tried to tell me "watch out guy, you're going to pass out soon, somethings gonna happen" My pulse started rising, i started sweating, and everytime I tried to breath calmly it fucking did not work! So I just began not thinking about it, I know it sounds realy tricky but. Just think of something other. Of something nice, happy. Or play a game. I always did that. Or i just watched something on youtube where I could laugh and just not think about this attack. And somehow, it took like 3 months, it went away, the longer the more. ... maybe that can help you somehow :unsure:
