Please help a flat chested person...?

I am fourteen-im aware im still growing. Im tired of being made fun of for my size and i want to find a natural way of enhancing them or helping them grow. I tried mage therapy, but after i decided to try it i realised that i dont know HOW to mage them. I dont want to wait. Im not super skinny either. I am a healthy weight and other than my chest size i am proud of who i am. I have never been more concerned about my personal appearence, so this would be a first. Im not super selfconsious lke most girls are. I also was wondering if wearing a size too small of a bra would be the cause of belated growth....Keep in mind im like a 34A. Thanx a bunch. =]
