How do I get my dad to leave me alone?

I absolutely can not stand my father. He is a rash, idiotic, douche bag. He favors my sister and always ends up against me for the 1 hour or so he is around. He can't stand me because I am not he perfect little pet, like my sister. I can't help the fact that I have ADD, severe clinical depression, and manic depression ( Bipolar if you will). Being a highly abused person at my school, punched, kicked, spit on, slandered, beaten, stabbed, etc, his domestic emotional, and mental aggression towards me doesn't help one bit. I did forget to mention I am 13. I have turned to many things to help with my issues, pills (prescribed, I took the dosages I had to, not abusively), meditation (which I do commonly considering that I can not dream) and "Legal Bud" just Google it. Anyway, I started to stray from my topic. My dad hates how I am joining the Peace Corps. and how I want to be an artist when I am older. He doesn't trust me one bit, and sets parental controls on my computer (which I get rid of easily) checks my txt messages, etc. The sad thing is that he never does any of it to my sister, because he thinks she is so great, even though she is a horrid, wretched, greedy, arrogant, snooty, fat, stuck up . So how do I get my dad to just go away (as in leave me alone) I just want him to go away, any advice on how to get him just to go away? I just want him to accept me for who I am, which I have told him to, he laughs and ignores me as usual, or just go away.
