I know your feeling. I ended up having my weight loss surgery in Mexico a couple of years ago to lose weight because my insurance in the US would not cover it. I think by the end of this year I will be going back to do a body lift or some other cosmetic procedure to remove the excess skin. Try talking to a company named MedPath Group its who I went through and everything went perfectly. I doubt you will find anyone to give you the surgery you want for free. But try writing into your local news station and maybe they will cover your story and a surgeon will see it and want part of that publicity? OR maybe write some local surgeons tell them your story and promise to promote them til the end of time if they give you an amazing discount.

Good luck
