I have a problem, but then I don't know if it is that big a problem. I have this voice in my head and his name is Zack and I don't know if he is realy there or is he in my imagination because I talk to him all the time and he does as he pleases and says what he wants he also gives me advice on life and what to do with the problems I have, but the scariest part is the fact that sumtimes he does as he pleases and at the moment he is filling my head with thoughts of hatred against all my friends by saying that they are all out to get me and that they all want to break my and my closest friend up a whom I also love more thatn anything else and sumtimes I'm afraid of what he might do because I don't realy have that much control over him. So is there any1 that can please help I think I need it.
