my mom. (help please)

she screams at me for the simplest things. the other day i forgot to put away my dishes after dinner bc i was rushing to finish hw. every day except for that day i put them away. for this, she called me a spoiled bitch, said i thought i had a maid, and yelled at me for 30 minutes, making me cry. i apologized too. she then screamed at me for crying and called me weak. at the same time, all my friends ditched me at school bc i hung out with a girl they didn't like. she called me a loser and a loner, and that i was nothing without them. you have no idea how hurt i got. if i text her and forget to say hello, even if i say it after she'll scream at me. im not blaming adhd as an excuse. but i do have adhd (diagnosed) and it's actually extremely hard for me to stay organized. i tell her it's hard for me to organize and i ask for help or tips but all she has done is call me a slob, a pig, and a disgrace. she always compares me to other kids but gets mad when i compare her to someone else. she mocks me and calls me names. whenever i hear my friend say they're best friends with their mom, i'm always jealous, or i think about my mom and wonder why can't we be like that. the main reason i like going to my friends' houses is because i know their house's atmosphere is nothing like mine. she never apologizes to me about the things she says and she never accepts my apologies, saying "i don't mean them". she has slapped me multiple times before. i honestly don't think we can get through a whole week without getting into a fight. i'm sick and tired of this, and she doesn't think there's anything wrong with this relationship. she doesn't want to fix things. she hurts me so much and she doesn't even care
