I don't know what your situation is, but if hospice is involved, talk with your hospice nurse. Hospice can help you arrange for respite. They can transport the patient to a hospital or care facility for up to 5 days per period. The hospice in my community has several rooms in the hospital that are strictly for hospice patients and the hospice staff arranges for all the necessary care while the patient is there.
If you are not in the hospice program, call them anyway. They may be able to supply you with a list of volunteers or people who will stay with your loved one, probably for a fee, while you get away for awhile. Each community's hospice program varies depending on resources, but it's worth a shot.
If you are caring for a senior and your community has a senior center, perhaps you could check with them as well. These centers do a lot more than play Bingo!
I can relate totally to how all of you feel about being unhappy and sometimes experience the feeling of what's the use. At this time, my mom is stable and things at home are on a fairly even keel. We are in the hospice program and they have been wonderful. But, I have no energy and I'm not happy. My full-time job is very demanding and I'm not happy at work but am too close to retirement to find something else. It's been suggested that I see my health care provider and perhaps get some Zoloft, but I can't bring myself to do it yet. So, I can also relate to the hesitation on taking meds.
Hubby and I are taking a few days in July to visit our son and his family, and my daughters will watch my mom. You are absolutely right ... sometimes just getting away from the situation for even a few days can do wonders. I'm really looking forward to it, and I sincerely hope you can find some help so you can have respite as well.
