Hello Khal and welcome to the Forum.

So sorry you find yourself here.
It helps to vent about the immature and abusive behavior. I know it helps me since my pwBPD is my elderly mother. I found myself suffering from depression and agoraphobia living with her as an adult. It was nonstop abuse exactly like when I was a child. It's a horrible reward for trying to help my physically ill parents. I wasn't even thanked by them.
It's good you have plans in place to move away. You deserve a good life. Living apart from my dBPD mom is a good baseline for my positive mental health.
