what to do when the economy collapses

I'm one of the fringe dominoes that is knocked over as the bigger guys crash left and right. Self-employed and not a plumber or doctor, I find myself face down in the mess.
What to do is keep painting. I spend the hours wrestling with the water element that is the dominant feature of this picture
Panic, done that. Rats-in-the-brain, ditto. Gone nuts thinking what I am employable as, ha!
Like I said, back to the paint.
Wish me luck.
