What the heck is wrong with my mother?!?

My mom CONSTANTLY yells and cusses at me. Whenever I don't know something she calls me stupid and lazy. Whenever I ask if I can hang with friends, I'm screamed at and told I need to get off the "party mentality". She constantly asks me every 20 minutes what I'm doing, and if I'm not cleaning or mowing or filling out job applications I get cussed at. I make a little mistake and she yells. She constantly calls me names and puts me down. So I'm constantly stuck at home, and NEVER get to do anything. I love mom a TON, and when she's not mad she's good to be around, but her yelling hurts me and I've just had enough. What can I do?
