I think my mom has an eating disorder and it might be because of my anorexia
I will get straight to the point. When i was in high school i developed an ed (anorexia) due to bullying and mistreatment throughout my school life. I was deathly afraid of gaining weight and started skipping meals and making comments like "even a small amount of milk makes me so full" or "an apple is a full meal", (ik i was insufferable) and it was pretty evident to my mom that it was disordered thinking and shortly after i got psychiatric help for that.
Recently, due to the popularisation of "sunken thin" bodies and extreme diet culture, i think my mom has started villainising certain foods and barely eats throughout the day. She talks about her previously loved foods like eating them was committing a sin, she talks about how anything with milk in it makes her full for half the day, how she cant finish a single apple bcs its too sweet, how anything with too much oil in it is straight poison, etc.
She was recently hospitalized because of digestive issues, and lost too much weight because of the same. When she came back from the hospital, some of our neighbours told her how good she looked and that it looked like she was a decade youger - which only fed into her disordered thinking and she started taking pride in getting sickly thin due to her illness. Today too, she bragged about how someone complimented her sudden weight loss, and i told her to not take pride in an outcome which was achieved through horrible health issues and literal life threatening amounts of illnesses (in the calmest way possible); she completely lashed out on me and started saying im making a huge fuss about nothing and that shes happy all that suffering made her thin and that im no one to give her any advice about anything. I am genuinely worried about her physical and mental health. All she ever talks about is food. All day, its either "did you know how bad this is for you" or "this is not good for yout gut" or "these supplements are super effective you should have them too".
Im going to be very honest, comments like these made me spiral back into my anorexia and later made me bulimic for months; but this isnt about that. I have gotten psychiatric help for that before and have been a part of ed recovery communities online that make me understand that thinking that way about your body weight and food is not okay. Even my dad and other family members have noticed how little she eats and when they talk about it she visibly looks impressed with herself. I have no idea how to approach this, every time i try to talk to her about this she panics, lashes out or shouts at me. I, too, avoid having any conversations about food with my friends or random ppl, having conversations about things like this is very emotionally draining for me too - so i understand her perspective, but i try my best to sound chill about it with her; but she is so dismissive and avoidant that it really makes me sad.
If anyone has any idea on how to talk to to a family member with similar issues, I would really appreciate your advice.
