Any kids/Scout troops/church groups in your area that might be able to help bathe the dog or help with grocery shopping? Or social services in your area - you might qualify for help, or they might be able to refer you to someone who can help for a nominal sum.

And BTDT with teenagers; fortunately mine were already pretty much grown by the time I was diagnosed. If it's any consolation, they DO turn into the most delightful adults - it's the "getting there" that's so frustrating....
