I can't stand my sister anymore
4 context I live with her and my mother and my parents divorced when I was 7 and ever since he lives in another city. We have money issues since our dad cant find a stable job and our mom basically provides 4 everything, something that my sister cant understand, shes 18 so my mom is trying to help her find a job but she wont accept none and tries to find excuses to not work, she gets mad at my mom 4 everything even when shes trying to help and is just straight up disrespectful, she hits, spits and screams at her constantly and acts the same as me, but then acts babyish and apologizes. She does this constantly, and by this point both my mother and I have gotten used to pretending to forgive her behavior but I cant stand it anymore, what should I do??
