Regarding getting any help from the VA, you have to be almost destitute, The elder can't have assets more than 85K(and that includes a house which disqualifies even lower income people).

Was your dad a veteran? There is a program "Aid and Attendance" through the Veterans Administration that will pay you if you qualify. Medicaid will pay family caregivers a small pittance. Or if Mom has funds to pay you a care agreement is necessary with taxes paid on it if Medicaid is anticipated in five years. Call your "Area Agency on Aging" within the Council of Governments they are a wonderful resource.
Keep in mind, whatever reimbursement you may receive, whether it is from a contract with your mom, or your state's M.A. program, it is taxable by Federal Income tax Social Security tax, and your state's income tax. The state will rrequire your Soc Sec number because they are required to report your income, to the Fed. If you rreceive private pay from your mom she needs to report it on Federal form 1099 Miscellaneous Income, so proper recordkeeping and reporting will be somebody's job to do as well.
In california there's a program called in home health servaces designed to keep seniors in their homes, for low income people, mostly on ssi. They pay 9.50 an hr and it depends on what services she requires
If your mom can afford to pay you what she would have paid outside caregivers for, and she should, then she you should go back to work and let your mom pay for her caregivers. Otherwise, no there is not a government program that is going to pay you for taking care of your mom.
