Great advice here from the ladies.
All I will add is to say think of yourself as a whole. Its hard not to concentrate on what we lack or feel we lack in our physical attributes but you are so much more to people than how you look. Pick out the things you like most about yourself or what you have accomplished in your life and be proud of those. When you are fifty your friends wont be impressed by tales or how great your thighs looked when you were twenty but they will be impressed by all the other amazing things you have done.
