says that if we get custody of SD it will ruin BD2 and NBD's lives.

Thanks for the support Mom!

I asked her why and she said because SD has been abused so she's not normal. I asked "So I should just leave her to be abused?" and she replied "You shouldn't have her around your girls."
Me: AND what exactly do you mean, she's been abused so she's not normal. I was abused!
Mom: No you weren't.
Me: So I'm just imagining all the times that [Stepfather] beat the crap out of us?
Mom: What are you talking about, it didn't happen that often.
Me: Oh my GOD, you are in denial. I've told you a billion times, every time you left the house it was free reign on [Dragonflies]! He'd smack me around until he was satisfied I'd learned my lesson then say if I ever told you he'd kill me!
Mom: You're wrong. You always had quite the imagination. I barely ever left the house anyway. I think it's time you leave

5 minutes later, she came in to my house (again without knocking. I swear, I've said it a half million times that I'd prefer she knock) saying I should come over and watch this show about people with multiple kids with her. Then she noticed a couple buttons on my [new to me] couch were missing. She went into this long rant about how even if stuff is free I should still take care of it. I must have said 100 times that the buttons were missing when I got it. She just kept talking over me and saying I need to take better care of stuff and that she was going to go get her vacuum :? . When I said, no, thanks, I'm a big girl now and I can take care of my own furniture, she stormed out. I locked the door behind her.
*Sigh* I wish my mother was normal...
