Help with my boobs???? please?

alright, i know i'm 13 and i'm going to be a freshman. and i started my period like three months ago. the problem is that everyone teases me because i have such small boobs.....and by everyone i mean EVERYONE. the reason this is because my mom has big boobs and my best friends have big boobs. But they alll got their period around 6h grade. i wanted to know if im going to have small boobs or not? im 13, weigh like 120 and 5'7. All my cousins grandparents and aunts have big boobs. do you think i just ahve to be patient for mine? one more thing, ow can i make them look bigger...i know the techniques like push-up and twisting the front. is there anything i can eat or something. i just get rejected by guys becuase of my chest and im sick and tired of it! i know i should be happy with what i got....but i got nothing.
