You posed an interesting question. I think if you are worried about being unhappy with looking too thin, then the surgery is not for you. However, Im almost sure that you will feel better about yourself when you lose weight because your energy levels will increase. My cousin and I have gone at it with each other about this very debate. She is much bigger than I am and she is content to stay that way because her excess weight is a part of her identity and losing weight would make her feel less like herself. I dont feel the same way. To each their own. I am making the commitment to health and in turn doing what is best for me. I hope you have the courage to stay by your choices to do what makes YOU happy.
