How do i get my mum to stop being immature and unfair?

My mum always thinks she is right about everything. She makes me feel like s*** all the time. She swears at me all the time calling me the worst possible swear words and she always says she hated me from the first days she ever saw me in her life. Its not my fault she had me. I think she blames all her life problems on me, her anger from her marriage problems is projected onto me. The other day she had a go at me for going in her room getting a bag of chips when she went in my room and looked at all my receipts and drawers. Because i had a go at her, she said she is no longer going to wash my clothes, take me to school or cook me dinner. Those are the only things I rely on her for, other than that i just sit in my room listen to music and study. I dont want to talk to her because she never listens and she is too stubborn to admit she was wrong.
