In life you just have to accept that some people are going to have some things better than you - some will be more attractive, some will have more money, some will be cleverer. If you sat there and worried about all these things, you would never leave the house or make friends with anyone. What you need to do is look at what you do have, not what you don't. You're friends don't soundy bitchy - their comments are probably just off hand comments that you have taken to heart because of your insecurities. You could always go out and find some less attractive friends but that's not really going to solve anyhting. You need to accept who you are and learn to love yourself.
