Again...Kelly has hit it on the head....a point I neglected to mention, and that is, there has to be a point where it "just clicks" in your head ( after much internal and professional discussion in my case) and you are mentally ready to take on not only the prospect of surgery, but more importantly, the behavioral changes and inclusion of exercise in your life that will be the KEY to your future.
I hope your "click" comes soon
peace,
