Long ago, I spent a year living without steady work, without central heat (in North Dakota) or running water, living off the 'king's deer', much of which was cooked over an open fire. Yes, funny things happened, there were a lot of laughs, too, and the idea I was not the only one in those straits helped keep me going.
I honed my skills at barter, I found spot work, I found ways to get by, and with time, things got better. I wish I had written about the back side of an oil boom, but doing so as a retrospective would not capture the experience nor have the weight of writing about as it happened. Boom and bust is part of the industry I work in, and only three winters ago I was shoveling snow for Christmas money. This year, I'll make six figures.
The first part of getting out of the post-layoff slump is realizing that your situation is temporary.
The second part is making the moves to pay the bills by taking temp work, spot jobs, even lesser jobs, only Julie can write about it, which ties in with getting back to full time writing.
It's hard to stay in a funk when you are doing what you love, and one of the best ways to get over being bummed about your situation is to be actively doing something about it.
YMMV.
