my mom called me a 'Ra*di' lol

yea, im (17F) currently in 12th preparing for boards, ab I also go to coaching toh Maine dummy college join kara hai, ab I had to submit my practical books toh I went to my college, I wasn't in my uniform (| went after school hours) because I also had to attend my coaching classes right after. tab hi my HOD who also happens to be my chemistry teacher saw me and scolded me for not wearing a uniform toh naturally, I said "im sorry ma'am it won't happen again" toh she told me ki "jab koi rape karke nikal jaayega toh woh rapist bhi sorry bol dega" hearing this I was obviously very pissed but I didn't say anything to her. instead I went outside the college and started ranting about it to my friend now, idk how but the HOD heard whatever I said (I didn't use any profanity or say anything inappropriate btw) Ghar Jake I told my parents and my mom simply said it's my fault i obviously broke down. ok now come day of the chemistry practical. she started humiliating me in front of the whole class berating me for the experiments and their results , and later tells me ki she heard everything . after coming home I told my mom about this and started crying she said ki this is what happens to stupid children like me and it's totally my fault because I must've said something to the HOD . now i tried to explain to her multiple times ki 1 didn't say anything but she won't listen to me so naturally, I started crying and said to her that she is unsupportive and it would've been better if she had aborted me instead (she said this to me before so I used it on her lol ) tabhi she stared hitting me brutally, dragging me by my hair and slamming my head onto the floor after which she called me a Ra*di and 'baazaru' for letting this happen to myself. now no one in my house is talking to me not my dad not my brother they are treating me as if I don't exist. I'm contemplating offing myself tonight since on one clearly cares about me
