ah i'm sorry you have to deal with that, biba. my mom had some boundary issues too but yours sound way more severe.

is your mother in therapy? are you? idk at some point if a person doesn't respect my boundaries, i reevaluate my relationship with them - like not cutting them off completely, but how much time i spend with them, the things i share with them, etc. but doing that with your mom may not be an option and is much harder obviously.
