You are all beautiful no matter what. Feel comfortable in your own skin. Don't let some standards and people crush your confidence and your comfortable skin. We are different, and that's what makes us beautiful.

Here is a trick:

      Every day, since you wake up to sleep think of the beautiful things you have done and say to yourself "I'm beautiful." because you are. Look yourself in the mirror and say "cute, beautiful, talented, smart" all positive words. You are beautiful, never forget that.
