help me

so i fought with my sister jn because i made a joke about something at her status and she hit me like out of nowhere and she was so mad she even decided to give my stuff that she bought for me to to other people and she even exposed me on instagram all because of that one joke and then my mum said "no wonder you have no friends" to me so basically I'm exposed to everyone and my family hates me overall and i want to confess my anger to my friends but my friends followed my sister on instagram and they probably saw her story exposing me... i already said sorry to her she hasn't replied yet but seeing all my family members being on her side and even saying that's why i have no friends hurts tbh yeah i live in a toxic household where i was always body shamed by everyone I really have no one to talk to maybe the internet could at least make me feel happy
