Medical fatigue

Couldn't find medical fatigue as a term, but after seven and a half months of treatments I can easily say that I am now at a state of medical fatigue. It is not the cancer per se or even the difficult treatments, it is the burn out of these never-ending hospitals, pills, appointments, fatigue, blood work, daily radiation, etc.

I am getting tired of being constantly exhausted.... though I think, I actually have it easier than most. I still manage to go to parties, birthdays, occasional concerts or even Cape Cod. I even managed to play a few volleyball games a week ago -- so I am more than half-way back to normal life, and it is still exhausting. 

People who have it harder than me, with harsher side-effects, or less of a support network -- I keep thinking, how do they do it? How do they stick it out and not flip the switch to stop all treatments and just do a life reset, at least for a while?
