TW: sexual assault by parent?

I'm a bit reeling right now.

My biggest problem trigger right now is my mother. She has a long history of inappropriate touching/"sneaking peeks", hitting, scratching, yelling etc when I was a child.

For reasons I won't get into I'm living with her right now. I finally got her to stop touching my ass, mostly by being on guard all the time.

But just now, there was lint on the front of my shirt and she fucking PLUCKED IT OFF fully touching my breast. I fucking hate her for this. I can't fucking stop being so angry at her over shit like this. And then when I react by going completely silent and leaving immediately, she sighs dramatically as if it's my fault she is a chronic sexual assaulter.

Please tell me if I'm overreacting or what else I can do about this fucking shit. I would go for a walk but it's so hot out I really cannot.

It makes me want to SCREAM. The feeling lasts on my body for so long.
