I'm sorry that sounds very difficult to live like that.She just doesn't know any boundaries, that's why I started writting here (she is bad with technology). I used to have a dairy but once she found it and started looking for it everywhere until I threw it away. She also checks on me regularly, and when she is on a crisis she does it like every 10 minutes and forces me to tell her exactly what I'm doing until she believes me.
It is tied to her depression too. She says that me, my brother and God are her only reasons to live, and as such we shouldn't keep any secrets with her. She knows every single of my friends secrets, even the ones that they haven't told anyone else but me and it makes me feel so guilty, as well as the moment she knows I have a secret she forces me to sit in front of her until I tell it to her, as well as having to help her make my brother "speak up".
Finally, I actually asked my mother once to let me go to therapy, but somehow my mother managed convince my T to let her be in the room too. It made me feel very uncomfortable, especially because once I made her leave the room with my psychologist (in a kind way of course) and later in the car she wouldn't drive until I told her what I said to the psychologist, I had to make up a gross lie in order for her to let me leave. It is really a big part of the reason why I can't get help.
How old are you? Is there a plan you can put in place to move out if you are an adult? If that isn't possible, is there someone you can talk to?
My mum has no boundaries either, and has a strange obsession with my body. I no longer will stay in her house. She not only tries to see my body, but also my partner's when we have stayed. I'm in my 40's now and she hasn't changed.
I suppose it's trying to carve out something safe for you whilst you are in this situation.
If you are a minor, can you talk to child protection services?
