One of my classmates used to laugh at my big breasts when I was at school, saying that it was particularly disgusting. Makes me feel ashamed of my big breasts. It's shameful. What to do?

In fact, you don't need to pay attention at all. You can take what she said as a kind of jealousy for you. Big breasts are a sign of a girl's good figure, which means you have a good figure. Why are you ashamed? Besides, boys like girls with big breasts now. You should be happy, not ashamed. Besides. You didn't eat his boobs. What's with the big breasts next to you? Does it matter to him? This kind of person doesn't have to pay attention to her. She is jealous of you, so she says so. Never mind what she said. This kind of thing should make you happy.
