Good Morning C....
In Haste: I had the same situation and took care of my Mother and Handicapped Brother 24/7 for nearly 10 years...in our home. I had to quit work, etc.
I got durable power of attorney for both of them and signature cards on bank accounts...had their Social Security checks set up for direct deposit and used their monies for their expenses...including our grocery budget. This was sufficient for me to manage all of our needs. Loss of my income made it a little tight, but it all worked out.
If you have any sewing skills, email me...maybe you can work with me from your home???
Hope that this helps...understand completely...praying for you and your family as I close...G.
