Does my mother sound verbally/mentally abusive?

yes your mother is being verbally & mentally abusive, u need 2 tell someone that u can trust to help u, a grown-up that will do something about your situation NOW!! i feel she's also physically abusive towards u 2-ripping your hair out!! you're not in a normal situation, so it's understandable that u feel that u hate your mom, she needs help, but so do you, tell a teacher/counselor, a priest anyone u can trust that will help u-your gramma an aunt or uncle, good luck to you
