How do you stop worrying about how you look or act?

Answer 1

If you are a teenager, just realize it is a very normal thing to think about those things a lot at your age. It will pass. One thing that I think makes it worse is that so much of what we see in the media (TV, magazines, etc.) makes it seem as if physical attractiveness is all there is to life. You can try getting your mind on other things, and get involved in things you are interested in. That might help to occupy your mind with better things. If you have friends who put too much emphasis on appearance, maybe you can find some who don't.
