My parents keep buying me food and it ruins everything

I know, I know. I'm their daughter, they want to feed me, absolutely normal and I'm extremely grateful that they're sweet like that. But it gives me so much anxiety, like please I told you I didn't want that so why'd you still buy it I literally don't fucking want it? And I told you I wanted to buy my own food from now on so why are you still buying me stuff I don't want? I want safe foods not chicken nuggets and 3 whole mangoes (yes, fruits are surprisingly fear foods for me). I don't want to waste food so I have to eat it but it makes it all worse I hate this so much just leave me alone I don't want food :((( I'm so grateful that they buy me everything but...just stop.

and here come all the people downvoting me of course like always!! like sorry i am sick and can't force myself to want food, sorry this stuff makes me anxious, sorry for sharing my experience??
