One of the best books I ever read was Sister Carrie, written in the early 1900's. I forgot the author (Theodore Dreiser?). It is about a once affluent banker who lost his job, and his slow decent into poverty. Of note was how he refused many jobs on his way down, because they were "beneath him."
I think the best medicine is reality, and your maintaining good boundaries so you are not sucked into the downward spiral. I say this to myself as well, because we have a couple of relatives in similar positions. I have decided what I will and will not do. I will offer food and a temporary place to stay. Every year we grow a good garden, and do lots of canning. I will not offer money.
There is a saying that comes to me these days:
"Money is relative; the more money, the more relatives."
