I'm usually peaceful, but sometimes I tend to get very angry with people. This guy tried spit in my face, and even though he missed, I still see him sometimes and want to knock him out silly.
Shuh, you don't know that. The internet isn't always right. No one in my family has had schizophrenia before.
Also, I know that one guy who took way too many drugs got schizophrena.
Anyways, I need a reason to stop.
It's possible they do, if they're anything like you they never told anybody. I'm diagnosed depressed not otherwise specified and last year was when I got really, really worse and I found out after seeing a psychiatrist that my entire family had depression, even my father. And I heard a story that my grandfather's father went insane and nearly killed his wife. You could have Schizophrenia, or you don't or you could be under a lot of stress. I diagnosed myself as a Schizo and bipolar but it turned out to be false. Don't diagnose yourself. If you really think that you have a problem then see a professional, If you're worried about telling your parents just ask them if you could talk to a therapist.
The relations between drug use and Schizophrenia is very hard to prove, it hasn't been proven before. So his case was either genetic or withdrawal from the drugs.
