I called my mom a piece of shit.

I was having an argument with my mom because she married a loser and she always puts him before us, meaning my sister and I. They had two children together and my sister and I are from the first marriage. She insisted we call him Dad. They married in 2003, shortly after he began abusing my sister and I. He would call it "discipline". And everytime he hurt us, she would do nothing... she'd yell at him and that it. His abuse ranged from beating us with wire hangers, kicking the shit out of us, using electrical wires as whips, cutting our hair and so much worse. As children we were afraid to say anything. I'm 20 and my sister is 19, and we still carry much of the emotional trauma with us to this day. It bothers me so much that she can easily brush it off. She's like, "if it bothers you so much, go get help". I would need help if you stopped it in the first place, no child would ever have to go through that! I'm crying right now cause I am so baffled by what we went through. She insists we move on, it's a thing of the past. I can't, I won't. 
Her first marriage was destructive too as my biological father would abuse her, she just married another piece of shit that abuses her children. It's frustrating cause everytime I argue with her about something, I throw this topic at her and she's so unphased by it claiming, "oh we are on this topic again?!"
Yes, it's not going to ever go away... you can't just brush it under a rug and forget about it. Today I got so fed up with her, I said," fine if that's how you feel about it... you're a piece of shit". And I just stormed off to my room. I don't think I can make her understand how much it still effects me and my sister, I can't forget and move on. I can't hold myself together when I talk about it, even to my boyfriend... I weep about it.
