idk what to do..

My mom and I have been getting into fights regularly and I'm starting to hate myself because of it. she always screams at me and never thinks of how what she's doing effects, other people. she only ever thinks of herself. she yelled at me earlier because of something so small. not ONCE has she even tried to sit me down and talk, the only thing she can do is scream at me over everything. she acts so differently in front of my friends and other people, but whenever we are alone, she's super rude and attacks me over everything and anything she can think of. I'm tired, and I don't know what to do. her words are starting to get to me and I'm starting to think she's right. that I can't do anything right at all, and that I'm never going to be good enough no matter how hard I might try. I've tried talking to her about it in a calm manner but she always pushes my boundaries. she tries to bring up things I am not comfortable talking to her about but when I say that she gets mad.

if anyone has advice, it would be highly appreciated
