can someone help me please?!

I recommend getting a bandeau type bathing suit.
they go straight across your chest so no need to show cleavage !
get one with padding, and if you want, add extra padding from a different bathing suit (there is usually an opening on the inside of the bathing suit for the padding to come out)

but other than that, don't worry too much !
have a good time with your friends, and don't think about it (:
just give it a year or two .. and you'll get "bigger" (:

myself, I went through the same thing a few years ago.

hey. don't worry about it, k? Big boobs are a pain for more reasons then one. There's not really anything you can do about your body type, except accept it. Look for the good things about your body. Everyone is different and anyone with brains will understand that and not look down on you for not having huge boobies, k?

I know you can feel a bit inadequate but I really wouldn't worry at all, everyone develops differently and if they are your true friends they are not going to worry at all. Be confident people are all different shapes and sizes and very rarely unless they are really insecure there selves will people take any notice at all.

buy a swimsuit that keeps the emphasis on your body, not your chest. Keep them interested a little lower than your chest.

I like to watch the Today show and they say stuff about this... im a nerd :D

I hate to say it but guys are guys and they'll probably be too distracted with the other girls' boobs to even notice yours. Don't worry about it, be comfortable in your own skin! :)
