How to stop feeling insipid!?

"Cut the mustard." I've never heard that before. Haha. I love it. Anyway, there are tons of people going through the same thing you are. First of all, remember that any body type can be beautiful, it's just a matter of how you present yourself. Try going shopping, that seems to help a lot of people when they get clothes that fit better and look classy. You could also try doing something different with your hair. Don't feel selfish, everyone needs helps sometimes. I hope this helps, best of luck to you. :)
