Worn down

Did 6 cycles of chemo (drip). Then did capecitabine oral for three weeks with radiation. I felt pretty good through all of this then during the two week gap before restarting the capecitabine I suddenly had constant nausea and fatigue. I returned to work. Now that I am back on the capecitabine I am exhausted. I have a small chronic cough and chest pressure that wakes me up. I am pretty freaked out as I am waiting on a liver transplant for my bile duct cancer. I just feel so beat down and wonder how you get a liver transplant after months and months of chemotherapy with some radiation thrown in.
