AITA if I block my sister from my life after moving out

Hey everyone I just wanted this out my chest after what happened last night I a (25m) am moving out soon from my sisters who’s (30f) while living with her I found out a lot of things that I won’t go into detail due to her having kids and my brother in her custody but while living with her I’ve been getting the short in of abuse and my boundaries crossed a lot. For a little context I was homeless for a year and came to Texas from California. To stay with family they we’re super supportive at first and I also stream and get into tournaments but last few months been hell. On my days off I enter then and win some cash and relax because I’ve been stress out and she’s been interrupting, cutting internet. And saying I don’t help out. Yet I work almost everyday, send money and when other people do something in the house wrong I get blame for it. Last night broke the camels back. I got woken up to help unclog a toilet and when she was like dont drop the water I was still dizzy from waking up and drop some. And she pushed me aggressively into the shower wall. I had dislodged my shoulder and hurt my ankle when that happened. Lucky I can pop my shoulder back but she was saying to me. “Your fucking useless, you never help out” yet I do the best I can while working and trying to stay awake since my sleep schedule is fucked from working 8 to 5am for 3 years at a club. But honestly stopped caring after last night. AITA For deciding to cutting her and everyone from her side out after what happened last night and everything before it?
