My husband just completed treatment for nasopharyngeal carcinoma, stage 4, 2 neck lymph involvement. It was definitely a rough road. I must tell you that the people on this website will help you in unimaginable ways. Stick with them and try all the suggestions. YOu just never know which one will work! It is so different for everyone and the more you know the better.
A wise person (NPC survivor) told me in the beginning that this whole thing in many ways was harder on the caregiver. In my case, I am grateful that this was not the case. But, I suspect it often is. What was hardest for me was simply watching what was happening to my husband and not being able "to fix it." As the problem solver in my household, I had to accept that this one wasn't within my power to fix.
After that, I learned to let a lot of things go. I accepted, for the first time in my life, help from friends and neighbors. Even now, they still help out with our nine year old daughter, take the trash cans to the curb, shoveled the snow, whatever needed to be done that I couldn't get to. I even asked the guy next door to carry the water bottle cases in for me. I just couldn't risk pulling out my back.
These things, as they come to you, you must pay attention to. Most of all, take care of yourself. Grab a book, soak in the tub, take a quick brisk walk with the dog/neighbor or whatever it takes to not "live cancer" for a little while. It will rejuvanate you!
The road will get rough but your hubby and family unit will be okay in the end.
My best to you,
