not sure what to do, please help

i’m 21 and recently moved back in (after living alone for four years) with my mom, two sisters, and little brother ever since graduating college to save money. my older sister does not do anything, and i mean ANYTHING. i help take my siblings from place to place, pay for their things sometimes, pay a portion of the bills, don’t ask for anything, pay for my own things, etc etc. my dad is out of the picture now so my mom is more stressed than usual and constantly angry at everyone. i never really talk to her because i honestly don’t get along with her at all. she is too sensitive and she has no issue taking out all her frustrations on me, the only person who ever tried to help her with anything.

recently, ive been fighting a lot with her and my older sister because i genuinely just dislike them and they also constantly make jokes at my expense, comparing me to my father and stuff like that. i recently told them i don’t value their opinions and that they’re irrelevant to me. they obviously understandably got angry and said that i ruin everything just like my dad used to ruin things. i guess what im having a hard time deciding is if i should move out? if i do, i know for a fact that i will have to go no contact because this will cause tons of drama in my family. also i would feel bad to abandon my younger siblings who depend on me. if you read this far, i appreciate it.
