Hi Sandy,
This is coming from a patients point of view. I worked during most of my treatments. My drs. even suggested that working is better than not. It helps to have other things to think about other than dwelling on the CANCER. In fact, I went to all my treatments, and all my dr. appointments alone. I continue to go alone. Going by myself makes me feel that I have some control. Crazy, but I feel in control. But to answer your question are you selfish NO, because you love him. But remember you both need normalcy in your life.
Best Wishes,
Dee
