Dad fell and is in rehab. This is his second full day there. He is in a lot of pain when he tries to sit up, and I think that he's very depressed. I plan to spend several hours there every day, both to cheer him up and to provide what physical help I can (the place appears to be somewhat short staffed). Any advice on what helped your parents when they were in rehab? And any advice on how to keep sane in the midst of all the stress?
