As a primary caregiver, Its important that you get some away-time/respite. You need to take care of yourself before you can give quality care to others. This may mean relying on other family members to pick up some of the duties.
Do you know or have a loved one who has a chronic or serious illness that is difficult to deal with on a day-to-day basis? How do you or they deal with the emotional stress to keep it from becoming overwhelming?
My youngest sister recently passed away after fighting cancer for three years, beginning in her colon, then vaginal wall, liver, lung and eventually brain. She kept sane, by starting a charity called coversforchemo.net and delivered snuggles and other comfort items to oncology patients, and getting the word out about how cancer affects people and how much help a little thing can do. Her daughter continues her charity.
