Kinda self conscious about this.

Ok so I'm only 15 and my boobs have gone up a full two cup sizes the past 3 months. I don't know how they're growing so fast. I'm a 38DD almost a 38DDD. Not trying to sound conceited but I'm not fat I'm average and even my doctor says my boobs are huge for how much I weigh. It makes me self conscious because people are always saying "your boobs are huge." I know it shouldn't be something that bugs me but people always stare and I don't feel comfortable having this big of boobs. 😞 Can you guys think of anything I could do to boost my self esteem?
