(Serious) Venting (Tw:eating disorders,

My dad screamed at me again today, I recovered from undiagnosed bulimia a while back. Id only really eat at school, and then id go to the gender neutral restroom to throw it up. My body never changed, I later learned my body type runs in my biological family (ex: my mom, brother, and sister are all heavy set). I was mindlessly talking about my weight, because it was bugging me, and then my dad said "just lose weight" and i said "ive tried, nothing happened" and then we got into this big fight, he ended up screaming at me, saying I was lying about what happened, and telling me to "quit my crying", I wanna purge so bad...and never eat again
