My mother has an ED, I used to have one too. She wants me to go back to my ED weight so I can “be healthier”

My (20 y/o) mother (58 y/o) has always thought I was fat. My health is just dandy, low iron but thats from something else. I’m as healthy as a horse, have some love handles here and there but who cares. Back in middle school I was anorexic, avoiding food like the plague so I could stay skinny. I’ve grown up, and now I can eat properly. it’s still a struggle to have a healthy relationship with food, but I’m getting there.

Recently, my mother has been eating less and less, then binging at night. She’ll eat half a tomato for dinner (tea and coffee for breakfast and lunch), then pound back a pint of ice cream at midnight. She insists I eat too much, and recently she‘s been cutting down my portions to absurdly tiny amounts. What do I do???? How do i explain to her that my weight is normal, that the pudge in my stomach is there to protect my damn organs? that i’m allowed to eat? that SHE’S allowed to eat???

if it helps for context, she used to work on TV, she was always skinny, so she thinks thats what she needs to be pretty. it’s bullshit.
