Best thing you can do right now is THINK POSITIVE! If you have decided that this is the right plan of action for you, then you should also decide that you are going to make it happen!
Park Nicollet has, IMHO, a great program - they walk you through all the necessary pre-op requirements (theirs AND your insurance plan). If you are a good candidate and there is any way they can help you get WLS, they will. You are in good hands. I'm over 5 years post op, maintaining, and happy as heck with what WLS has done for me physically and medically. No more diabetes. No more back pain, no more foot pain, very little knee pain (old injury - lots better than it was, but will never go away without a surgical fix.). I can buy clothes pretty much anywhere I want, and I am no longer paranoid in front of people. Men - older AND younger - have actually hit on me! (What a strange thing!?!)
Just get your head on solid, and dedicate yourself to the changes you will need to make in your relationship with food. It's quite a ride!
Imperfect does not = unsuccessful
