It always makes me sad to know someone is unhappy with their life. Life is meant to be enjoyed. You have a pretty face, I'm sure that when you smile it lights up a room. You can change your body if that is truly your desire, it won't be easy. You've already found that out. You do mention having friends, keep them close and you will not be alone. My only advice would be to seek peace within and make small but steady change a persistent habit. Forgive mistakes but don't make them a habit. Most of all, care about and for yourself, your life has meaning and value to yourself and those around you!
Be well!
