I had and still have the same problem. I used to weigh myself after every meal. Then one day I saw myself in the mirror and I saw something that was pretty and before that my mom said I was pretty then I thought about if I wasn't pretty how come I had two boyfriends and all these other guys like me. Then I though it was all in my mind, I'm looking at myself as what I wished I looked like and not how pretty I am now. Some people are just meant to be big but they're beautiful big. You should not compare yourself to the "standard" beauty society shows but mind yourself that you are pretty as you are. Once you see that then your mind will show your real beauty.
