First I would say find something that you are good at that you like to do. A hobby, Art, Sport, computers, mechanical? Working on a hobby can create a sense of accomplishment and self worth.
Realize that what makes you different and unique also makes you beautiful.
Don't give into the hype from the media. Most images you see have been tweaked, photoshopped, and not everyone has a stylist to make them look good.
and last but not least. get to know yourself and love yourself for who you are.
