Is there anything i can do to reduce the size of my boobs?

Im 14yrs. Im 12D ( in New zealand sizes). Girls in my year have boobs but mine are huge compared to theirs. I always dread Phys Ed at school. They are bigger than my mums. Aparently i will grow to like them when im older as ive been told. So is their anything in the meantime to reduce them a bit? Just so i can have someself confidence back
