When will I stop being so flat?

Im about 13 and I am flater than a wall! I get made fun of all the time for having no boobs, all my friends are C-B cups and I dont even need to wear a bra. My moms a C cup and both my sisters are B's. I am skinny and I dont know if that has something to do with it..but my friend weigh's so much less than I do and she has a B cup. I know I'm only 13 but when will I grow...why does everybody else grow and I dont??? Please help! is there anyway I can get them to grow???

Nothing To Worry About.
You Can't 'Force' Your Boobs To Grow, At Least Not To My Knowledge.

Breasts Tend To Appear With The Onset Of Puberty. Perhaps Your Friends Started Puberty Before You.

(Assuming You Havn't Hit Puberty Yet, You Normally Tend To Around 13 I Think. I Was A Bit Younger)

I Use To Worry About Having Small Boobs At Your Age Too,
But Really Just Relax About It.

what the heck is wrong with you?! you don't need boobs yet! so a few people feel insacure with themselves and have to make fun of you about it, so what! their the ones with the problem, not you! besides bras are uncomfortable and annoying, you don't want to wear one until you have too

don't panic, females grow at different rates and big breasts aren't always as good as what you think... your breasts will grow don't worry.

I wouldn't be too worried- I mean, you're 13. Puberty hasn't finished with you yet. I hit puberty quite late, and I didn't really get boobs until I was about 16. Don't stress it, they'll grow in when they're good and ready. In the meantime, you can be happy that you can wear pretty strappy tops braless- what I wouldn't give to be able to do that again!

Well,most of my friends make fun of me because I have small boobs.^^
But of cause there are way to make it bigger.Do eat papaya.To me it helps.Good luck to you! ^^

Some girls don't finish developing until their early 20s...
