Help... im a 15 year old girl who needs advice?

My advice is don't lose weight and don't go back to 75 lbs. I am 5'3 and 95 lbs at 32D-23-33. I wear a size 0 and you are basically calling me fat because at 90 lbs you feel fat. You must wear a 00. Why on earth would you want to lose any weight? What size will you wear then? I mean, I think I have a killer body but some think it's too skinny and doesn't look good. Don't you want to look good? Stop being silly, it's fine to workout a lot at the gym but when you are 90 lbs and trying to lose even more weight, that's just silly.
