Liz - My husband had a terrible time post radiation and chemo with depression. It took a village to get him to admit it and finally he broke down in front of his doc and was put on anti-depressants. It helped with his morale, his eating (he wasn't gaining weight) and his emotions. She explained that it wasn't a reflection against his manhood and that 75% of her patients suffered from depression post treatment(and the majority of that group were men). He is on anti-depressants (for 6 months) and they have helped immensely. He calls them his "crazy pills" - cancer humor! Those weeks post treatment are the worse so hang in there and if you think he needs help - call the docs.
As a side note, I am taking them as well. With his treatment, runnning our business, being available to 3 elderly parents (one with Alzheimers) and the normal day to day life, I was not doing too well. It didn't hit me until he started feeling better - I guess you run on adrenaline for so long and then WHAM! So, take care of you, too!
