Permanently hallucinating?

okay this is the story. i used to do weed, spray, legal herbs and salvia a lot. spray as in inhaling deoderant and what not. i used to trip the **** over it and i used to always control my subconscious to do odd things like change my blood temperature. once on salvia i had a trip where everything made complete sense in the world. 5 months ago i decided to stop doing all of it because all id get from every one of those was bad trips like things crawling over me and things hitting me. i used to always trip with static you see on a tv, it would all bunch up into a little ball and attack me like an eagle. everything was fine when i quit it and my life was getting better. then one night about 4 and a half months ago i had a fan in my room. it started echoing and talking to me. i freaked the **** out and went upstairs to have a drink, i didnt actually know if i was in a dream or not because when id bite my thumb, my body would automatically numb it right when id bite it. it was the freakiest **** ever. anyway. ever since that day ive been on a permanent bad trip. ive tried risperidone but its done nothinig. its all just paranoia and i know its all in my head, trust me, all i think about is answers and theres an erge in my mind that actually likes the bad tripping. thats what makes it so hard. i think this is a type of skitzophrenia.. ive contimplated suicide because this really isnt fun. its just me in a constant game with my sub conscious. i even got a tattoo on my chest saying "control the subconscious". so yeah my question. has anyone been through anything remotely like this? and if so, is there anyway out of it? feel free to ask any questions as ill be happy to answer :)
