I think my boyfriend is going thru something similar. Its been almost 4 months that hes been parinod, delusional, hearung voices, violent outbursts cause of the voices (he couldnt hear them all clearly and he would get aggrieved and break and throw things). He is a crystal meth user (approx 5 yrs). Weve been togather for about 7 months but I've known him for probably 3yrs. Usually he's very sweet, quite, loving and caring but this state of mind he's in now us very similar to scizophrania. He think (he believes) everyone wants to hurt him somehow, including me. He wont eat food that he didnt prepare himself, use opened hygiene products if already opened, etc. He keeps anything opened locked up. He has broken every electronic device (tvs, cell phones, speakers, xbox, etc) because he believes cameras or voice recorders are watching him. And voices would tell him very false untrue things about me cheating and working with someone to turn him in (he thought I was a CI or being blackmailed). He got so bad a week ago that he almost killed himself. Hes been baker acted and is being released today. His mom and visited him yesterday and we both agree he still isn't well. I dont know much about drug induced psychosis but I've been researching alot (that how I seen this). Good Luck to you, just wanted share this story with you.
