As a Cancer Patient myself 3 times, and as a caregiver for both my mom and dad when they died from cancer, bless your heart, and thank you for what you do!! It is tough, I know, but please know that it's tough on him seeing you have to take care of him. Since I have been on both sides I can say easily, that taking care of Mom and Dad, was harder on me than me having cancer, as far as how I felt. It was tough on me seeing them fight. And at the same time I know the feelings of having to have someone wait on me hand and foot. You are a strong woman doing great things, you too, are a hero.
And your post brings up another thought, maybe we need another category on the right under "filter questions by diagnosis" and include "caregiver".
Good luck to you both.
