Finding help for husband and myself, advice?

It like pulling teeth just to get some place to help us in Nevada.
On Aug. 9 we went to eye doctor for a tune up. My husband who has
Macular Degeneration and knew this, was told he has a very aggressive
dry Macular Degeneration the doctor said. Told my husband not to drive,
and also inform him, he would lose his sight in 3-6 months. My husband is
one of these people who like to keep busy and help me around the house.
I do not know how to handle any of this future stuff he is handling over
to me. Also the eye doctor told him to stop taking the vitamin pills for his eyes
because they will not help him anymore. Both of us have retired and don't know
anyone except Walmart the would hire me, I for one have a bad hip and knees
and can't stand for 8 hrs. a day. The worst to this is that his
father is living with us and he is 92 yr. old. He has his own medical
problems. We both are his care takers, I can not care for the both of them .
Looking for benefit help, tools for husband, and support.
