Given that I'm not a psychologist or therapist, I don't know much about the disease or even his diagnosis, but he is paranoid and talks of his phone being tapped, hidden cameras, has grandiose ideas, claims experiencing things that could only be hallucinations, and makes illogical connections. He has a history of drug use (heavily uses marijuana, has prescribed medicine). He doesn't always behave in such ways, and is 'normal' most of the time. If I recall correctly, his father was diagnosed with bipolar disorder. My father never graduated from high school and can't do things such as spell even simple words. My mothers side of the family has no history of psychological disorders. I can't even begin to describe how profoundly scared I am. I just graduated from high school and am attending college later this year and I shudder to think my life could be ruined by inheriting this frightening disease. I'm 18 and, and -- as far as I know -- don't have any cognitive dysfunctions. I used marijuana casually from ages 15 to 16, but stopped abruptly and made the decision never to touch drugs of any kind again (alcohol or otherwise). I really appreciate any advice, knowledge, or websites you can provide. Thanks.
