Wow, I am sorry. How does one deal with that sort of thing?
My parents were/are infirm, but my sister care(d) for them and most of the rest of us watched out for them, took to the doctors, bought groceries, all sorts of paper work, etc. There is no way they could have done it alone. Hope you find someone to trust.
Sorry ... Glum today.
Found out my childhood friend who now lives in Maui was mis-diagnosed. When he found out he had stomach cancer, he just killed himself.
Today is heart breaking.
