I seriously hate my joint family right now.

I am not posting this for karma it's not fair my heart just feels too heavy.I live in a joint family and honestly, I hate everyone here except my mom, dad, and brother. They’ve made our lives hell we can’t eat, speak, or even sit peacefully without being abused. Today my brother was making Maggi. He went to buy sauce, got a bit late, and it got slightly burnt. My uncle the “leader” of the house came shouting, cursing my brother for eating Maggi, body-shamed him saying “kauve jaisi shakal ho gayi hai Maggi kha kha ke, haath pair agarbatti ban gaye hain phir bhi bahar ka khaega.” My father and grandmother joined in with their usual taunts "sara din andar baithe rehte hain ghar mein kya jal raha hai kuch nhi pata inko". That same uncle is an alcoholic who fights with his wife every other night abusing her cursing her and everyone in the house because of which no one can sleep. His daughter got typhoid from junk food, his obese son eats out constantly, yet he keeps lecturing us about “health" mocking and body-shaming us pretending to be concerned. Recently he has started targeting my 14-year-old brother falsely accusing him of breaking an AC pipe on Dusshera (when the AC was fine because they literally slept in AC same night) anddamaging his activa when he himself told her to use his activa because my brother always uses my father's activa and next morning himself comes and says "isne nahi kiya hoga ye itna sukha hai isne thoki hoti toh ghar nhi aa pata. My grandmother pretends to care but only adds fuel to every fire. She calls herself educated, retired government officer pretends to love my mother but says things like “bacche ko kitchen mein jaane dete ho, maa-behen nahi bana sakti kya?” and gets away with everything even when she herself burns milk in every few days. My father is a good dad but a terrible husband short-tempered, always siding with his younger brother who's treats him so terribly snatched away his business and his wife who's a bitch but never my mom. My mother is breaking down. She wakes up at 4 am sleeps at 12 at night, brings milk for whole house at 5am, cooks, walks 2 km to school to teach, comes home, and does all the housework. She is already skinny and has lost more weight, she’s dull and silent now. She has no favourite food, desire or anything to make her happy she just wants peace. So much work is destroying her health she can’t leave her job because she’s scared she’ll go crazy listening to my grandmother taunts all day. I try to help my best does chores secretly when she's at school because she doesn’t let me much because of my studies. I just want her to smile again, to rest, to feel peace for once. If anyone’s lived in a toxic joint family and has gone through the same, please tell me how can I make my mother a little happy.

TLDR : My joint family is super toxic. My uncle and grandma constantly insult my mom, dad, and brother, and I’m watching my mom break down slowly while doing everything for everyone. I just want to make her happy somehow.
