I'm so sorry to hear how rough it's been for you, pal. But this weight issue, for diabetics, is crucial. Counting calories sucks and it annoys me tremendously how few we actually need everyday to sustain life. (Truth be told, nobody needs ice cream every day but once you hit your weight goal and the diabetes is managed a child's cone once every couple of weeks really tastes spectacular!)
Your CES can prevent challenges in the physical activity arena but your doctor should be able to help you find a therapist who can work on a plan for you. Walking in well visited stores with wide aisles is perfect for you. Just pace yourself, okay?
It's good to see you posting and if you need some pipe projects to work on, please let me know. I can send several your way.
Here's to a strong finish in 2014 and an infinitely better 2015, friend.
