My Mom and I both went through it when we cared for my grandmother who was dying of cancer. The most important thing is for you to take care of yourself, too. Caregivers need breaks and down time to cope with the emotional, physical, and mental stress of intensive care of a loved one.
We finally arranged for my aunts to take turns one day a week so we could just get out of the house for several hours. Then on another day one would come so Mom could get bills paid and the grocery shopping done.
