Marie, I kinda know how you feel, I have all kinds of doubts.. Like Sharon, said, find out all you can about the surgery, ask questions. I am also 5'8 and weigh 314 and rising.. I am 57yrs old, I have Grandchildren I want to see grow up. At this stage of the game that is very likely. I was so embarresed one year, I had taken my two Grandson's to the fair. Michael, wanted to go on a ride, but had to be with another person or an adult. They tried 3 different cages for me.. I was to big to fit in one, this was in front of a lot of local people that I knew. I don't have to tell you how embaressed I was :(. God will be with you in what ever decision you make... I have surgery the 27 of this month... if you need to talk to some one please feel free to contact me....
I'll keep you in my prayers...
