DP/DR + psychosis

it all started in highschool, i had some problems with a gang, i received death threats, got beat up bad, and decided to change schools. My life suddenly changed, i didn't know what was going on with me, but i had my first attack of dr and dp. everything was weird, i was in a dream, i was the only person in the world, people were staring at me, when i looked in the mirror i saw things for a few seconds, things that went away a few seconds later, those things were like my hair was ugly, i was ugly. I didn't understand. But it all went away, but not forever. one year later dp came back, dr did't. Until today(now i'm 21) dp is a part of my life. But it doesn't end there. when i was 18 i started smoking weed for 18 months. a saw a psychiatrist, and he perscribed anti-depressants. a few months later he perscribed anty-psychotics but told me to stop smoking weed, which i did. so basically when i started taking anti-psychotics the first day, i stoped weed. 4 weeks later dr came back, but not by itself, i got pscyosis too. I don't know what caused the pscyosis and dr, was it the weed or could it be the anti-psychotics. Anyway i stoped taking anti-psychotics 4 weeks ago, because i got really dizzy and a lot of headaches. 20 minutes fter taking the anti-psychotic medication, i started experiencing psychosis and dizzyness that was unbearable, fainting. Weird? anti-psychotics causing psychosis features and dizziness after taking the tablet? I think i have over-active dopamine receptors, could this be the reason, or something else, the doctors don;t know anything, i have decided to help myself, please help
