Re: I hate my chin!
Yes! Of course there is! I suggest finding some before and after pix related to what you want, type "chin reduction, before and after" into google and you'll see that it's possible.
And who knows, maybe your parents will let you do it sooner rather than later. I know what it's like to feel the need to "fix" something. And if this is all that's getting you down about yourself then it will help you feel better. Don't listen to people who say plastic surgery is "fake". They don't realize what you're feeling.
But also try not to let it get to you (I know, I hated hearing that). Sure high school is fun and important, but the real important stuff is after high school. Just remember that you'll be in a different world in a few years and this will all seem silly. And its not something that can't be fixed, it's so doable!
