I think I might be developing it, I'm 17, and I've got almost all of the symptoms. At times (today in school for instance) I just get a sudden change of personality out of the blue and don't know what to do with myself, when this happens all I really want is to be alone. My personality in general has changed over the last 6 or 7 months, lately I always act hostile towards my family too, my mother especially (which I feel like an asshole about), I feel like she's nagging me whenever we talk. I've also lost any motivation to do well in school or other activities, I feel nihilistic most times, not really caring about much of anything, with the exception of when I get mood swings (if that's what you want to call it) which usually only last a couple hours in total, but when I have them I feel paranoid, confused, basically I have no idea how to act or interact with and around people. Then at other times I act overly hyper and joyful, which I don't mind, but it's very out of character for me, seeing as to how I'm usually a fairly quite. When that happens I'll talk to someone I don't even know, or speak to anyone without even thinking first (I almost always think before I speak). My sleep patterns are messed up too, I always feel resteless, and when I do sleep I can sleep for the majority of the day. I also drink frequentley (according to my pediatrition I'm an alcoholic), and I use drugs (weed for the most part, I occasionally do shrooms, nothing heavy), and from what I hear that can increase your chances of getting Scitzophrenia. I've looked around on the net and I think I could be in the early stages, I hope not though, I'm afraid if I get it people will treat me differently, in fact I know they will. I don't want everyone to have a different opinion of me or to think I'm a lunatic, if you're Scitzophrenic or if you know anything about the disease can you give me your opinion? It'd be appreciated, thanks.
