What's wrong with me now?

Ok I was a fat girl in high school and no one would talk to me so I didn't really have friends but I went to military training and lost a lot of weight I have a body like a Victoria Secret model and you know how some of them are then with like a c cup and no butt that's how I am and despite me being skinny people are judging me about my butt!! Like they saying your hot gorgeous face nice body but where your butt you need to do this and that to get a butt I'm tired of that but yet you can sit there and talk about how nice the models look so I'm wondering what's wrong with me I have a ton of insecurities
