I learned in April 2011 that I had CNS lymphoma in my brain, but am now in remission. Shortly after i was diagnosed I met with a psychiatrist and he prescribed an antidepressant drug. It was very helpful to me during that very stressful period. I was comfortable to discontinue the drug a few months later.
There are many issues from this disease even after it is in remission. I've had to adjust my lifestyle because I missed eight months of work and the income it provided; I'm working again but just part time, making less money. I also don't have the same level of responsibility at work and that's a difficult change.
Physically I have a significant loss of strength and stamina - I took huge amounts of steroids and they caused a lot of muscle damage. Since I was a very active and enjoyed outdoor sports, I really miss feeling strong and healthy.
Naturally the fear of recurrence also causes a lot of stress. I try not to think about it, but some days I can't keep it out of my mind.
Emotionally, It's hard to start feeling normal again. I feel like I've taken so much from my wife, my family, my friends, that I hate to ask for more of their attention, but it's hard to get by on my own sometimes.
Those are just a few of the issues, so it's not surprising that your husband may be depressed. But things do get better, a little bit every day. I'm in better shape now than I was in December, and I plan to keep improving mentally and physically.
Good luck to you and your husband.
