It's really bad that your mother would do such a thing to your father or her own child. She's supposed to be the one that protects you and that you can run to when you have no one else. It's really hard to go through life and not being able to trust anyone just because your mother turned you against yourself. I know how it feels to be screaming for help and no one listening because my mother would convince them nothing was wrong. She would give them her side of the story, but, since she's the parent she has the voice not the child. Which, is very wrong.
I finally just left because I couldn't handle it. I watched her mistreat my dad and then she'd make fun of me. If you disagree with her she'll have everyone in the family and household on your back about how she's right and you're wrong.
It's hard to be in the situation that you're in. I don't understand the point of having a child if you aren't willing to love it and not hurt it. All I can really tell you to do is try your hardest to survive because it'll show how strong you are. Then the first chance you get, leave. Don't worry about who will be mad, worry about yourself because since no one else can save you, all you have is yourself. If you need to talk I'm here.
