Boob size..

I am 19 years old and I'm so self conscious. I am on the heavier side of most girls, but my boobs are the problem. One boob is way bigger than the other, like ones a D almost DD and the other is a B. this makes me so uncomfortable to take my shirt off in front of any guys,. Like I'm still a Virgin and haven't done anything because of it.. should I really let it bother me that bad..?
