Both my parents are gone I am the only grand child and I left my home in Florida to come to NJ and take care of my 100 year old grandmother. nursing home is not an option for her and my cousin and aunt who were taking care of her can no longer take care of her. How do I avoid burn out?
Caregiving is like having a full-time job in itself, especially if you are unable to get a full nights sleep. I was working full-time and my aging parents lived in their own home [mid to late 90's] and could fend for themselves, but running errands in my free time, burnt me out before too long. And I was taking too much time off from work and that caused major issues at work.
Why is an Assisted Living facility not an option? Is it the cost? If your grandmother can apply and be accepted by Medicaid, she could go into a nursing home, Medicaid will pay for her care. But at her age, if Grandmother can afford caregivers, it's better to keep her at home.
The only way to balance working outside of the home and caregiving when you get home is to set boundaries. But it is so hard to say "no" to ones elder :(
Often this respite is provided by family members. When that is not possible you need to make other arrangements. Did/does GM belong to a church? Can they arrange some home visits? Is there a volunteer organization that supplies companions for a few hours at a time, for a nominal fee? Paying for a few hours or a few days of respite now and then can save your sanity. (This should come out of GM's funds.)
