You might try the nursing department of your local college or university. I don’t know the rules there, but at my school, we were required to do many hours of community service to obtain our degrees. We ran blood pressure clinics, led exercise and recreation programs at nursing homes and adult day cares, and other stuff. I bet a couple of nursing students would be pleased to help, whether they got school credit or not. (Another option would be the physical therapy department.) People go into this line of work because they truly care and love to help.
Does your friend receive home health services? If so, ask the nurse to help you find the resources. (If not, call a home health agency and ask them if they have any ideas. They will almost certainly be willing to help.) Home health agencies rely heavily on social workers, who know every program in the area and can get your friend hooked up.
And how about you? Moving a bedbound person is no easy task if you don’t know how, but if you know someone in the healthcare field- a nurse, nurses’ aide, paramedic, x-ray tech, physical therapist, or whatever- maybe you can enlist that person’s help. If not, maybe that person can give you a few lessons on body mechanics so you can learn to move your friend without injuring either of you. (It’s not about strength; it’s about using leverage.)
A support group for cancer patients and their families would also be a good resource. I imagine many people have faced this same problem, and found a solution they’d be happy to share with you. A call to the hospital social worker should get you in touch with a support group.
If your friend is a member of a church, perhaps this would be a good source of volunteers.
I’d also check with your friend’s doctor before taking her anywhere. Cancer patients have weak immune systems, and exposure to the germs out there “in the world” could make her very sick. Perhaps, if risk of infection is a problem, the doctor would give his blessing if your friend wore a hospital mask out when in public. (Let people stare.)
It’s wonderful that you care so much for your friend. Getting out and about can give her more hope and strength, helping her to keep her spirits and fight her illness. If she does lose her battle, she will have spent good and happy times with a special friend.
