This post on Keep Working Girlfriend (a site about coping with chronic illness) talks about the difference between being the illness and having the illness. This is true of any illness.
It's an interesting and powerful topic. And I agree with it to a good extent, but as I posted in the comments to it, it's a realization that happens over time--being the illness for awhile to learn to control it is a good thing. I'm not saying stop your life, but it's a new awareness into something that permeates everything you do. It's only when we learn about our limitations and feelings that we learn to move past them and back into our roles at home, with family and friends and at work.
