I had a psychotic break in 2009 and was very homicidal, I was brought in by the police peacefully to a mental hospital and put on anti psychotic medications. I had problems with psychosis starting in my early teens, I am 30 now. Being passive aggressive I am prone to bottling up my emotions and then exploding. I started smoking pot everyday after I got out of the hospital, I feel that it really helped me process a lot of things that happen to me growing up and to deal with them in a peaceful-non-violent way, through marijuana and spirituality.
How marijuana effects you though is different with each strain. Some relax you and make you a couch potato, some strains give you energy and you want to go for long walks. I would recommend Jack Herer, it is very motivating, you will want to clean the house and do something productive. We are sick we when don't want to leave the house, are paranoid about answering the door or the phone and don't want to be social.
It's because of smoking pot that I have a good group of friends, they all smoke too, we do smoke sessions to enya and dead can dance music. I hate to say that mental illness is a gift, but we can use our experiences to help other people, and when you smoke you can get deep into though and process things. I find street weed to be stoner weed, increasing my paranoia and ptsd symptoms.
