Am I Schizophrenic?

I'm 13 year's old and have already been diagnosed with ADD and depression, but ever since I was 9 and 10 I acted weird, I was bullied for my weird behavior in 5th and 4th grade. One time when I was 10 I thought I heard my dad call my name from outside and he was actually downstairs. Last year in 6th grade I was really paranoid and tense for the whole year, I starved myself to under 100 pounds. My dad didn't seem to care or notice my other family said I looked "better" for looking like a emaciated dog. Anyway I also might have Bi-polar because my attitude shifts mostly and at night or evening I get really hyper sometimes and laugh. But also get depressed and suicidal. I only live with my brother and father just how it is. Recently my mother got into a accident I haven't heard anything since. Since I was about 10 I used to bite myself and eat lotion (Gross I know.. :l) I didn't have many friends and was online more. I have a horrible self-esteem and bad confidence. I have a strange phobia of famous people (historical to) but mostly like someone is out to get me or make fun of me. I had bad nightmares about getting stabbed and left to die. I am alone most of the time, and my father is either arguing with me or leaving me alone. My right now is pretty depressing it's spring break and I still don't have anything to do. I'm not a complete loner but I used to cut myself on my arm and hips, which I stopped cutting a few weeks ago. I'm sorry if this depresses you It's just my life.
