i feel your pain trust me, i have had my period for 3 years, i have quite a developed body (hips, ass) but i'm quite flat chested. Only one of my brests fills out an a cup properly, the other barely does. It probly isn't healthy but i wear push up bras majority of the time and i always chose bathers with halter strings coming from the verrrrry side of the bikini top and ALWAYS padding :) 

i know it sounds shallow and insignificant, but it makes me feel much more confident and clothes sit much better

~Why worry about knockers that'll be dragging on the sidewalk when you're 50. Grow up and worry about your brain instead. A well developed mind might get you fewer dates than will overdeveloped mammary glands, but at least the guys you do go out with you will be more apt to want to see again. Or, you can go in the other direction. The guys won't care so much about what's up top so long as they are sure they can get into what's down below. [Given your issues with size, though, set a minimum length that you'll give it up to.]

I feel your pain as well. It makes me feel like i'm not a woman and like i'm a child:( it's quite embarrasing when picking out bras or a bikini cause i can't even wear a bikini :( What can we do? Going to the doctor is embarrasing when you try asking them for help all they say is "oh that's just the way you're built" i'm pretty sure there has to be something wrong..?
