Vent, kinda dumb tho

TW: Animal abuse? Child Abuse. Neglect?

So, my mother just beat the shit out of the dog for pooping on the carpet and I think it went too far, I get the spray bottle but she doesn't have to smack him. I don't know why but watching that gave me such bad flashbacks to when I used to get beat and I think I've had a panic attack for the first time in 4 years. Ever since I stopped giving her a reason to hit me, she's been way more snappy and it kind of freaks me out. I do believe she has Bipolar or BPD or at least narcissistic like, I had just seen my dad for the first time in five years and she's like "Do you like him more than me?" Bitch, yes I do. He's not around enough to actually abuse me. Ever since she got rid of her ex husband and started dating again, it's just gotten worse and she's just gotten more narcissistic. I think its because there's someone who will agree with her no matter what and she can't actually hit me in front of him so she just gets snappy. Or I'll be in the middle of a nice conversation with her and I will ask a simple question about something that's happening or I need and then she yells at me for no reason. I don't know what's happening to her, she used to be so nice, or I was just being abused worse by her ex husband to realize her abuse as well. If anyone knows what's happening or has a similar situation, I'd be open to talking about it with people in similar situations.
