I think im gonna stop eating two days

I always feel so disgusting after I eat. I feel like slop, or that I’m way larger than I am. Last time I was weighed I was 173 I know I’m probably so much more now. I rub my tummy and feel how huge it is and I want to cry, I’ve bought things to workout, I tried to eat healthier but nothing has ever truly stuck like I so desperately need it to. I don’t wanna give up on myself, I’m so young. Do any other teens struggle with this or anything like it?
