New to Communty- seeking help

I just discovered this website and i feel somewhat comforted by finding a community of people who all understand this. I’ve been experiencing depersonalization since I was 14. The day after Halloween of 2020. I had a bad high and woke up the next morning feeling dissociated for the first time. It never went away. I’ve done everything J can to try to talk out past traumas or ignore the symptoms but I haven’t gotten any relief in those two years. sometimes it’s so bad I cant respond to my surroundings and I cant think. I’ve found nothing that helps me at all. I’m looking for any coping methods past those on regular websites because none of them will work. I really, desperately want to find relief as I don’t think I can live like this anymore.
