As you have no doubt read in all the previous posts here, your husband is going through a normal response to the treatments and psychologically to the disease. What you must try to understand, and really cannot help him with, is that he is mentally adjusting to the reality of his own mortality, and the fact that we are all physically frail human beings. It is a normal response, and while it happens to all of us that go through a brush with cancer, we males, seem to have a rougher time with it. For myself, it was tough to go through the long recovery process from it all. Months into recovery, I wasn't feeling any better, and more and more things kept happening to me. It seemed like one step forward and two back all the time. The doctors told me that I was cancer free at the end of treatment, and I was happy. That lasted for about a week, as I then started to feel sicker and weaker. As the weeks turned into months, I grew progressively weaker, and my mood grew progressively darker as a result. I was a horrible patient...angry, scared, and grumpy to say the least. These days I have a greater appreciation for what my wife went through during that year of recovery after the radiation and the surgery, and how much of my terrible mood swings she had to deal with. He is early in the recovery process, and this is unlikely to end soon. All you can do is try to be supportive and patient with him. For me it helped to finally midway through the process start talking with a psychiatrist to explore my feelings about what had, and was, happening to me.
