Can't sleep maybe I should go for a drive.

As I toss and turn in bed I am afraid of what lies ahead. Medical issues stink and I feel like they have got the best of me. At what point do I decide to have a surgery that would enable me to exercise. Should I wait until I have reached my goal or should I do it now? When I heard the news today I wanted to go to food and drinks for comfort. I have mixed emotions and all I want to do cry.
