Grandmother's been staying with relatives and running out of options. Hospital has to release her, where does she go on a fixed income?

Grandmother is 93. Her daughter is blind and not able to care for her. She is visiting but will soon need to leave her. She is in a WA hospital that will not hold her as she is perfectly healthy.

She has lived in an independent property but neighbors have exhausted trying to help her and avoid her knocks on doors at 3 am. Property manager has suggested nursing home, but she does not qualify for LTC in AZ as she is not bed ridden, is what we were told.

Already 2 other grand children have tried to care for her but it is impossible. She is up all night and is very erratic during day. She is fine one day impossible next.

What states of AZ and WA have told us is there is no money or services to care for her. What NYC has to offer is long waiting lists.

She is 93 and literally wandering the country staying with relatives a bit at a time as she does not want to return to her Phoenix, AZ apartment, which is probably not the best option. Has anyone run into this problem?
