When my father was in the last stages of CF, my mother was completely consumed by my father's condition. She wasn't sleeping, wasn't taking the time to eat, wasn't doing anything for herself. Things that made a difference:
1. Ask her if she wants to go to lunch, do some errands, take a walk. Just something to get out of the house/hospital for just an hour or so.
2. Having ready to go meals. Although again, she may not eat. . . .
3. Hiring her a cleaning service, someone to come in once a week, to change the beds, do laundry, dust, wash the floors. . . .
4. Reading materials - magazines, something to take her mind off, but don't require too much thought.
5. Does the car need an oil change? Is there yard work that needs to get done? Any quick, easy home improvements? Changing light bulbs, etc. This is all something my father use to handle and when he couldn't anymore, this was a huge blow to my mother.
I hope this helps
