My husband had his left lung removed on 9/16/10 at 37. he did three months of chemo, and the doctors are very pleased with the way his right lung expanded, and his scans look great. the problem is he is angry. I try to encourage him. to excercise, and be positive, but I just get you will never understand. I know I won't ever fully understand, but I see my young vibrant husband angry and sad. We have two kids and long lives ahead of us. any suggestions?
