I was a critical care RN when I had the big excacerbation that made me quit work. I am glad that I did not have to make the decision myself. The disease itself did. I was just never able to get back to work. But being off work took such a stress level away my body could concentrate on getting stronger. I know though that if I went back to work I couldn't do it. Shoot, I can't even remember a password for an internet site without writing it down.
