Can someone please tell me what is wrong with me psychologically?

I was just wondering if all of this stuff I'm experiencing is normal. I'm 15 and I have alot of weird stuff going on in my head. First I have weird dialogues with myself. In my mind there will be one "person" who I sometimes equate as evil or "the devil" and while I can't tangibly hear it it still seems to have a mind of it's own. Second there's me, I talk out loud to the one in my mind. I can also think independantly in my mind but the other is still in there and argues with me alot. Third there's the ever present "God" who never directly speaks to me but gives me certain impulses like to pick up trash or impresses guilt on me whenever I "sin". I should make clear that they. Never impress anything drastic on me like hurting someone but they're constantly at odds with each other and me. Another thing that I wonder about is my morality. I don't understand anti drug sentiments and I know what drugs do to people. Also I don't have a problem with stealing or lying and I don't understand love. When someone says "I love you" I don't know what it means. I don't understand love at all. I have a massive adversion to my own parents particularly my father and will NOT under any circumstance allow my skin to come in contact to his. He's never hurt me or anything it just bothers me to come into contact with other people. The only person who I have any affections for is Anne Frank, who we all know has been dead for a very long time but I'm still very obsessed with her and write to her in my journal because if love is real then I feel it for her. Please help me what the hell is wrong with me? Please help in addition to avoiding my parents I also fear their judgement I can't see a psychologist or talk to them about it.
