What are our options for additional financial assistance? Sending her to a home is not an option.

My Mom (85) dementia, who has been an invalid for the last year receives some Soc Sec and small VA benefits, but pay for her 24/7 sitters. Rent, utilities, etc. has been coming out of her savings for the last 2-3 years. Monthly expenses have always exceeded her income and her money is about to run out. Sitters alone are more than $1400/week even with children assisting shifts. PS - hospice currently provides supplies, etc and visits once a week. Thanks.
