Your question is very broad.
The web link is to a page from the Aging Life care Association, a national organization of health care professionals who have skills and knowledge to help people find assistance needed as we grow old and ill. The link will tell you about individuals in your area.

One of the local members came and talked to our neighborhood "eldertea" meeting, talking about the range of options available when we need help. She didn't charge for this.

And she stopped in our home to assess our environment for aging in place. Because we are close to major universities and medical schools, there are many resources, including health care majors who provide basic home help at minimum wage!

You'll have to try the link and see who is available in your area. (just enter your zip code.)

Since you are facing multiple illnesses, I hope you'll find someone soon who can help you plan your future needs, at home or in a care facility if necessary.
