Juanita do you know why Joann's husband has so many appointments? If he has cancer she should check out if The American Cancer Society free rides to appointments is available in her area. Lyft also offers free rides. The appointments have to be cancer-related, though. Or if he is disabled he could perhaps look into city/town services' medical shuttles that pick people up and bring them to appointments etc. and bring them back home. No one person should have to shoulder what she's going through.
