How can I apply for getting money to take care of my 87 year old Mom?

We are both on a fixed income S.S. and she needs constant care. My father was a veteran of World War 2 he passed many years ago I am the only child of my parents and I am a 69 year old male. I have been taking care of all my mothers needs the last 10 years but recently they have become much more I regulate her insulin, and other medications, take her to and from the doctors appointments I take care of her bathing, her transportation and her meals. We recently had to move because I ran out of my savings and we are in a motel. I was told that I can get paid for being her legal caretaker please give me any information at all that might help, I have a friend typing this on her computer because we do not own one.
