I have heard of a social securety benifit that will pay a stipend to a live in caregiver. Is there such a program in CA?

I care for my 90 year old grandmother in her home. She has some short term memory loss and severe osteoporosis and arthritis. She has about 15,000 a year in income from social security and investments. She owns her home free and clear. I am in RN school and make about 5,000 a year at my part time job. I have reviewed the social security web site and have been unable to find any reference to such a program.

I would be grateful for any sugestion
