Because sadly being your age is supposed to be fun, but it's not. It sucks, you just have to wait it out and not get down on yourself. Don't worry about being popular either, it's pointless.

You haven't had the chance to realize how amazing you are. Just wait until you find your niche in the world :). Try working hard at trusting yourself and believing in yourself, no matter what others say.
