Small breast size. Also make fun of me.

Hello Doctor, I am a 27 year old female software engineer. My problem is my breast size is very small for my age. All of my friends have an ideal size. Basically I am a B cup while most of the females around me are C cup or D. I feel very conscious about my small breasts. It leads to under confidence also at times, most of the times I feel intimidated. I always feel that no clothes I wear suit me because of this. I constantly keep wishing that I was C Cup at least. I also at times feel that my boyfriend would be wishing the same though he never tells me. I have tried homeopathy and ayurvedic for months now. Did massages and excercise. But nothing has helped. My period is also very regular and on time Please help me. I feel very depressed sometimes cos sometimes my friends also make fun of me.
