I'm a middle school student with no breasts at all.

To be honest, I have no intention of getting breast augmentation because I'm scared, but the kids around me have lowered my self-esteem because their breasts are much bigger than mine, and my sister and mom seriously say that my breasts have no volume at all, so what should I do? Is there a place in Daegu that does breast augmentation well? I'm going to do it when I grow up, but... is it better to go all the way to Seoul? To be honest, I'm not sure if I should have the surgery. I feel like I'm doing it for other people's eyes + the boyfriend I'm going to date when I grow up, rather than for my own satisfaction..? I think the fit of clothes would be better if I had breasts, but fat grafting is really bad because it feels like fat is entering my body. If I do it, I'm thinking of getting implants, but what are the specific side effects? Are they very severe..??
