Why would a mother hate her daughter?

Okay, so this sounds kind of insane but not only myself but some of my peers and also some adults have noticed that my mother is completely fake with me. She will use little what we call "stingers" little sentences that can be defended as caring or even just no big deal but have special meaning to me and hit me in just the right spot to make me super mad or sad. After she does all that for a long time and it causes me to freak out and not be able to be around her any longer because it hurts so bad then when i try to remove myself from the situation she makes herself into the victim so that everyone is upset with me and i have little choice but to go back to the house with her even though I'm so close to being out of the house it almost shouldn't be a big deal if i move out. Last time i tried to leave because i couldn't take it anymore she convinced my sisters to say that if i didn't move back i couldn't see my nieces who both mean the world to me. I've made mistakes in the past and she uses my old boyfriend against me a lot because we went through court because she read my diary and called the cops when we had and she hates him because he smokes cigarettes even though other then that he goes to my church every weekend and has a good job and graduated last year and I'm graduating this year but he already did college because he did a vocational college and is already at a higher pay grade then most people in his profession. Why does my mother hate me? i don't get it because i don't get what is so wrong with me?
