Bigger cup size?

Question

I'm worse than an A,  I dont have enough to even fill an A bra. I can't  wear  brallettes right and I hate push up bras cause I feel fake. Mean even Kim Possible has more boobs than me xD.  What have you tried that helped gain more on your girls? 
Ps. I'm  21 years, 5ft 2 and 101 lbs
Thanks with love.

Answer

Girl I'm the same. I'm pretty much completely flat and can't fill an a cup either and I'll be honest it sucks. Makes me super self conscious. 
However, I've never had a boyfriend who didn't like my boobs anyway. I have plenty of other features that are beautiful. Everyone hates something about their body. There is no cure, other than surgery. The best thing to do is just learn to love and accept your body.
