Hey dude, hard truths incoming. Sounds like you might have really fucked yourself - what you're describing seems a hell of a lot like schizophrenia. See if you have any family history of similar mental illnesses. Using psychedelics that young can seriously damage your brain, sometimes permanently. As soon as you can, go to you GP, start going to a therapist, and stop taking psychedelics until you're at least in your mid 20s. Sorry if this sounds harsh but psychedelics are not something to fuck around with, especially as you're still developing. I don't mean to talk down to you but this is just biology. Sorry bud, I sincerely hope you can get back to somewhere close to your normal self. Keep the peace.
