Granted, I was 20 pounds lighter in high school and my body structure was more ideal than it is now...but I'm happy because I'm finally "developed".

I know how you feel though. I went through the same thing--the guys don't line up like they used to, so if a guy calls me beautiful, it's a compliment that's hard to take. I usually call him a crackhead for saying such a thing...either that or he has his beer goggles on.

I think it's just a phase that you'll eventually grow out of. I was dreading my 23rd birthday this year, but I got over it after a while. Enjoy life now and don't worry about how it was before. You see life differently now and it's much more "real" than it used to be--and that's a great thing, because you finally can appreciate things for what they're worth.
