Another idea that's since come to mind -- thanks largely to folks also helping me -- is DHHS or Department of Health and Human Services. While I'm overwhelmed with so much happening simultaneously, others are arranging for in-home support services.

I can't recall when/where I read it, but it has been repeated by many sources is that it's not good for a caregiver to be the primary one around-the-clock. There is a burn-out factor.
