Sister makes food i don’t ask for and gets mad

So today we went to eat lunch with my dad, and I ate way more than usual and i felt super disgusting i only wanted to workout and not eat dinner, and i told my sister maybe i would eat a salad with just tomato and cucumber just so she wouldn’t worry, she proceeded to make a huge salad, full of stuff that i didn’t want and i never asked her to make it, and every bite i took i actually felt disgust, and my mom came to the kitchen and said “if you don’t want to eat the rest call me and i’ll eat it” so i called my mom and my sister got mad and said “impressive” the worst part is she’s had bulimia before so her judgement is making me freak she should know better than anyone how much of a mind fuck an ed is. it’s making me so mad.
