Lowkey need advice
So recently I had a so called 'argument' with my mother. Basically what happened was that I came home from an exam and just needed time to decompress so I clearly communicated that to her she took it as my exam going poorly so that's when her anger kind of began cuz i remember her screaming that 'your exam cant go poorly you have no choice.' well i was too tired to dwell on it so i took a nap. After i went to her and started talking to her abt my exam and abt how it actually went well i was just a bit tired cuz my dad came to pick me up around 30-40 minutes later than the expected time and i had been waiting there (ps there was a sand storm going on) so i wasnt feeling that great. While i was talking to her she was acting kind of strange but i ignored it like she had been dying to hear how my exam went and she barely gave a reaction when i was telling her abt it. When i was concluding my story i asked her how she felt now cuz she told me she was stressed and she said 'oh im normal now' and i was like oh ok great and was like soo what do you think like do u think i did well and she was like you have to i did this this and that for you and i was still kind of on edge so i went like well its ok i mean it wouldnt rlly affect you it would affect me more but she took this as an insult and started being all weird and she went on her agenda of 'your life is mine' to which i said 'i mean its my life' and she asked me how it was my life and started talking abt how she sent me to school and did all this stuff to which i said that it was her responsibility as a parent to provide all of that for me to which she had no other response than to repeat what she said before. I then started to change the topic to lighten up the situation and it was all great and she was also acting kind of normal-ish and even asked me more stuff but while i was talking she started going on her phone and started texting and stuff and got all excited (she is never this excited when i tell her anything even when i achieve smth) and i peer over her shoulder to see what it is and its my baby cousin crawling this obv ticks me off and i say smth like 'ok if u wanted a baby not an adult kid why did u have me' in english she took it the wrong way cuz she doesnt understand english properly and thought i meant to insult her and she went batshit crazy started yelling slamming doors cabinets throwing stuff around i just went to my room and didnt rlly do anything yet she escalated the situation to the point where she started saying shit like 'oh once you pass twelfth grade im gonna get u married off like ... mother is doing to her daughter (ps that person is old enough to get married and its only an engagement for now cuz both of them are in uni but she just loves creating her own little senarios cuz her married life doesnt statisfy her)' she then went to work and had enough free time to feaking msg me stuff on whatsapp saying stuff like oh i disown you and stuff and that getting u educated has had no use cuz ur useless and ill mannered (another ps ik annoying but she has been physically abusive ever since i turned 5 and verbally abusive ever since i can remember and her words hurt more than her weak ahh hits ever did). Now the next day she has been on her 'i have disowned my child' agenda and she seems quite happy to disown me and stuff and is like once ur exams end you have to move out of ur room and into either the TV lounge or the living room (i know its her just trying to take things from me to assert dominance or smth i just dont know what i did to make her hate me sm she has been like this ever since i was a little kid) and has been talking about how 'oh im gonna sell her gold im gonna do this blahblah' i seriously dont know what to do or who to go to so yeah
