Mom problems😬

So my mom just got out of an abusive relationship with my father. (This is the first time she's ACTUALLY LET HIM GO. Considering the fact that she's always let him back in even though she says she's done with him using drugs and coming back.) So we've been w/o him for 2 weeks now🙌🏾. But she's kinda taking the anger out on me. I will be getting disciplined and we will not have an actual conversation liked we talked about.(I'm 12) instead of it being like we're talking out a misunderstanding, it'll be like she's constantly yelling at me, not listening to what I say about what she got wrong.(I try to tell her things in the most respectful way). AND she'll send me upstairs to get some thing, stop me and say something to both of us (she wants me not to move when she's talking because she finds it rude) then RIGHT AFTER she's done talking she says "Go and do what I told you!" Like I had gotten distracted. ( I'm also supposed to say "ok" or "ok mom" after she says something to us, I was waiting to say OK)

Ok so that's my lil rant...any advice? (I'd rather have advice from a bunch of women than from some 12 year olds)
