Are you trying to care for someone who has qualified for these services?

Here is more info you listed:
"I am caring for John , who is 60 years old, living at home with age-related decline, alzheimer's / dementia, diabetes, hearing loss, and incontinence."

What is an EDCD Waiver that you posted in your profile?

I would search online based upon the issue the person you are providing care for has, like national organizations, foundations, blog groups, etc.
