Hello..I'm 16 years old and I was wondering whether I might have some sort of Schizophrenia...I don't have hallutionations..But I do hear loads of people calling my name and when i do respond I am told nothing has been said. I do imtate people's movements and speech alot without thinking. My friends and family know me for having many different personalities and now I usually have a habit of changing my mood very quickly, like sometimes I can feel extremly depressed but then I'm laughing hysterically. I find this frustrating sometimes but I can't help it. An its probably important to know my uncle is Schizophrenic and family has a history of mental illness.
