Nice that you’ve gotten some commissions. That must feel great!
Have you ever tried to work through a temp agency? Sometimes they have positions that can be for a day, a few days, a month…blah…Most likely it won’t be super interesting, but it could be. Plus, unless you are offered a job thru that, you only need to fill out an application once. And doing different things and meeting different people could give you inspiration for art and writing.
Have you gone onto job hunting websites like Indeed? Great for the imagination.
