Hi Anne Marie,
If you are like me, the early going was the most fearful and the most difficult. My imagination went wild with all the worst thoughts and feelings of pity for myself and my family.
As I learned more about the disease, and you need to keep asking your doctors everything you can think of (now and throughout treatment), the fear began to subside. In my case, my wife was my caregiver and attended each and every doctors visit - she helped a lot in the question department.
Once I got into the routine of the treatment, my emotions came under much more control and I found a lot more strength than I ever gave my self credit for (with a lot of help from my wife - I didn't discovered this forum until after treatment).
I do not have the same form of SCC that you do, but you are not alone - many here have experience with common elements that will be in your treatment plan, and you will find support and knowledge to help you through.
Best wishes,
Chris
