Can I get financial help for taking care of my mother 75% of the time?

My mother is a breast cancer survivor, COPD and Empysema patient, and she also is getting older, of course. I do everything whether it be bathing, helping dressing, ordering meds, making sure she doesn't trip/fall, utilizing her Neubulizer machine, driving, etc.
I love taking care of my mother but I/we need help. Financial help. Gas isn't cheap and I don't get reimbursed for taking off work. I just need help financially.
