My two biggest fears are the same as yours. Something going wrong, I'm a widow, my children (ages 13 and 15) have already lost their dad to cancer, they need me, nothing can go wrong; and second, failing at losing weight again. I've looked into this surgery for about five years now. After much research I know the surgery risks are minimal and I'm positive I'm going to be ok, and second I am determined to lose this weight, the band will be my tool to success. Good luck!!
