My mom expectations are too much and I have been suffering alone in silence for too long

So my mother kinda throw a bunch of tuitions at me since age 3+ cuz I guess she wants the best for me. after a few years i wanted to take a break from all the weekly tuitions So I said No to going and all my toys ended up in the store room and was dragged to tuition crying. (I have no allowance whatsoever so all my toys was from birthdays Christmas and I never got them back). After failing to meet her expectations in a major exam she kind of gave up on me and started loving my sister more and saying they still got hope. I think my mom maybe sexist cuz she keeps saying girls stronger than boys (to my 2 younger siblings both female) and that boys are meant to fix all the lights and carry stuff. my sisters are also toxic towards me like one of them keep saying shut up when I want to talk this causes me to isolate myself in my room gaming (which I love and my mother despise). Turns out it didn’t help cuz my sisters one time paste a paper on my door saying prison and my mother keep calling me a game addict which my sisters also learn to do. now when I talk to my mother I made sure to careful say what I want (My mother won’t stop bragging about her self learn cooking skills and one of her dishes wasn’t that good but I didn’t say anything for a while but one day when i told her that I couldn’t finish cuz I don’t really like it she got so mad and say she will never cook this again and gave me the silent treatment some cases expecting an apology). If that wasn’t bad enough she now also ignores what I have to say or tell me to zip and says she never lies although when we point out all the time she felt to keep promises she says forgot. But i still feel the pressure of making her proud (and also thinks she forgotten the whole reason why she wanted us to go well in school is for a good future) but all my achievements goes well done and forgotten the next hour . She always encourages me to ask questions in class because she assumes I am an introvert (I yap a lot on topics i lobe to my friends but she stuck in her reality of me being quiet) and when I ask her questions she give me the death glare and annoyingly say what. also I warn her my sisters is going to be way worse than me but no she didn’t listen cuz I am the ultimate evil playing games in his rock as a teen. Well my sister even before becoming a teen alr started stealing money from my Mom and me swearing a whole lot and insulting me so many times (which my mother never do anything about other than calls me sensitive) now I finish another major exam and my mother been saying I only play games and never show a single sign of affection unless I am extremely unwell (smth she will be hella angry that I am so troublesome and that she Would not care about me if I wasn’t her son) and now my sister been bullying me more oftenand my mother always thinks it my fault (also the reason why my father not doing anything cuz my mother listens to absolutely no one and also takes my sister side) also little does she know how many times I thought about how I can end everything (everytime I been angry or sad I just bottle it all up and it keeps coming back when I feel negative emotions)

TLDR: my mom gave up on me after placing insane pressure and expectations and gets mad at me frequntly and expects me to carry everything cuz I am a boy and also my sisters bully me and my parents takes their side and I think my mental health a little unwell. and I can’t talk to my mom about anything cuz she listens to no one
