I have zero conclusions on my situation. My Schizophrenia defintion from my readings says that it can be confused with dual personality disorder, that some patients have multiple voices contemplating within themselves, and have some case of anexity, both of which I am victim of(anexity being the worse).

The voice in my head, which I have done heavy thinking about seems to be a friend of mine in college and in high school. He is the other "personality" in my head. But I cant be sure, I really cant.

My family on my fathers side seems to have history of anexity, my aunt has had really bad anexity attacks.
My family seems like its filled with alcholics, my father drinks and a consistant rate and is addicted to ciggerates, along with his older brother(which may or may not have to do with anexity).
My dad, aunt and uncle are brothers and sister.
My grandpa also has a history of alchol abuse. And looking at my extended family beyond that, I cant seem to find any other correlations. My mothers side has no serious problems that I can identify.

Alright and here is the curve ball, I have recently started to smoke pot, and my anexity has been ridiculously reduced, and I feel like I am more in control of myself then I have ever been. Pot is the only thing I do, nothing else.
What the hell is going on with me? or am I just being a normal 19 year old?
