Is she on drugs by chance?

My mom passed away when I was young, but I was taken care of by siblings and experienced this similar thing. Eventually I thought "maybe I'm just bad" and that I deserved it all. It was the main reason for my depression. I actually never thought I would have made it passed age 16 so I never made a future for myself. I moved out at 18, but I tried to keep contact because they were "family". I finally had to cut them out a year ago and it has been a lot better.

CPS would get involved and they put on an act as well.
The way I got through this was basically dealing with it.

Do you have any way to record what she's saying?
It would be helpful than just you telling someone that it's happening. Get it on recording and confront the counselor. Express you are afraid to even go home and all your fears.

I hope everything goes well for you!
