If you could stand it, I would see if you could find someone who needed temporary "aftercare" from being in the hospital, maybe an older person who just couldn't go home alone yet. I don't know how you'd go about finding such a person, maybe a social work agency or just by advertising. That you're talking care of your mother would be a plus for them, I'd think. But with the first person you could see how it goes, knowing it would only be temporary (4-6 weeks) and you could then decide if you wanted to do it again or adjust how you did it, etc.
