I'm caregiving my aunt (85). Is there any financial support?

Who is paying the other people who come in to help, or are they all volunteers?

Is your aunt on Medicaid or eligible to be on Medicaid?

In a growing number of states, there is an effort to keep elders in their own homes, as being a less expensive option than care center placement. Many states have programs that use Medicaid money to pay for some in-home care. For example, the elder may be eligible for a few hours of cleaning per week. Maybe they qualify for someone to help them bathe once or twice a week. Perhaps an aide will be be authorized for so many hours per week.

In a growing number of states the elder can choose how to receive that service and one of the options is to use the money to pay a relative. Often the program case worker will have the relative go through an agency, to be sure all of the tax details get worked out.

I don't know how this works in your state, but you certainly should check it out. If Aunt is on Medicaid now, then the person to talk to (with Aunt's permission) is her case worker. If she is not now on Medicaid, start with your state's Medicaid website, and learn whom to contact from there.

It is true that a huge number of relatives taking care of elders are doing it as volunteers. It is also true that a large number of them have put their own financial security at risk and are going to be in a difficult situation (for them and for our country) when they retire.

If your state is one of the growing number trying to address this problem, by all means, take advantage of that!

Financial support for you or your Aunt? You could check with the local Council on Aging to see what is available for your Aunt, but since she already has people coming into the house she's probably already on board with what is available.

As for payment to you... the vast majority of grown children/nieces/nephews are not paid unless the elder pays them themselves. If this work is starting to become overwhelming, and it will start to be more demanding as the elder gets older and less mobile [maybe some hearing and eyesight loss, too], your Aunt will need to think about moving to a continuing care facility, unless she can afford to pay 3 shifts of caregivers to be with her.

Could your Aunt afford to have a cleaning crew comes in once a week? That would relieve a lot of time for you, or are you doing the cleaning to fill up your time while at your Aunt's home? Cleaning is such a thankless chore :P As for groceries, some areas offer on-line shopping for groceries with home delivery.

In california there is a program called in home health servaces exactly to keep seniors in the home paying for what you do. They assess the needs and give a certain amount of hours weekly

This is the #1 question asked on this site. Check under the Money tab at the top and read Paying for Care. Short answer is that most caregivers will NEVER receive payment from the state or federal government to caregive relatives - presumption is that you are doing it for love and family duty. You can set up a personal care contract for your family member to pay you directly from their funds prior to receiving Medicaid. This needs proper documentation to make sure that you pay taxes and provide documentation to prevent any Medicaid lookback issues.
