Still have to be sure of yourself. You didn't do anything wrong, but confident girls are the most beautiful. Besides, being fat is only a temporary thing. I used to be laughed at by the boys in my class because of my baldness and acne, but they made a joke about their own shortcomings, which really made people unbearable. I have alienated others many times and dare not take photos with my classmates and go out to play. But what's the use of being afraid? The more you feel inferior, the more you will be looked down upon. No one will pity you if you don't work hard. Be good at discovering your own bright spots, or re-cultivate a small hobby and gradually become confident. Besides, maybe your method is wrong. It is not difficult to lose weight as long as you want. If you like, you can come to me and I'll take you to try to lose weight. It's half a fitness instructor, haha. Moreover, you may not know how confident and beautiful you are after losing weight.
