What is the form name to be paid by Medicare?

Mom on Medicare paid home hospice. Can't be left alone. Father can't do it alone. I took a leave of absence: (laid myself off) from my part time job to help father care for my mother who is on home hospice. She needs someone with her 24 hours a day due to her medical conditions: Acute-on-chronic Respiratory Failure; COPD. & Congestive Heart Failure. I live more than 100 miles away, so I only go home once a week and return the following day. I have almost depleted all my savings and will be forced to go back to work if I don't get some kind of income. Medicare is her soul coverage provider. Do they have a form or application to supply some kind of financial assistance for care givers who are also family members?

NOTES:

1) Moving is not an option.
2) PT Job schedule is non negotiable.
3) Even if I help on my days off. Hospice can't provide the amount of home
assistance (babysitters) to allow my father enough resting time to regenerate.
