I am a senior, I have no children, siblings or family to help me when I am in my last stages of life and can no longer make decisions for myself. My friends are my age or older, so they won't be able to help either. How do I go about finding an outside party that I can trust to handle my medical, financial and all my decision making needs when I can no longer take care of myself.
These should be able to help you
An Elder Care Attorney should be able to draw up any papers needed for POA's as well as Advance directives.
Is there a trusted Clergy person that you can select to be POA?
If you are living in your home, alone would you consider moving to Independent or possibly Assisted Living where you will not be alone? There would be people to monitor you on a daily basis and if you are in Independent Living when they see that you can no longer do some things for yourself a move to Assisted Living would be made easily and you would get more help. Most Communities have a Social Worker that could help you with some of your questions as well.
When the time comes Hospice is a great way to get the care you need and the help that you will need. And again a Social Worker, Chaplain and the rest of the Team would be there to help.
A similar question was asked prior and received some responses.

Grandma's idea is a good one. I have a community where I live and they are probably all over the Country. My Aunt lives in such a community in Fla. The one where I live has cottages or apartments you can rent. This is the independent living. When needed, you transition into Assisted Living. When your care becomes more than the AL can handle, you then go into the LTC section. There is a buy in that is partially used for your LTC. When that is gone, then the facility applies for Medicaid. I am just giving u the basics there is more to it and I would have a lawyer read the contract to make sure u understand everything. I know several woman who have gone this way now they are widows and one has no children.
Communities like this usually have where you get your meals. So no cooking. My Aunt lives independently, but has access to aides if she needs one, at a cost.
I would suggest finding an eldercare Lawyer. One who is versed in Medicaid. He can guide you into what you may need.
