I worry about having to look for a job too, but my fundamental issue is that I want a job I can enjoy. Of course I would like to make money too, but I would never sacrifice pleasure for money. My ideal job would allow a lot of creativity and wouldn't involve too much face-to-face interaction with rude and unreasonable people. For this reason I would avoid the service industry like the plague.
If you can pass a background check, are reasonably physically fit, and want *lots* of time to read / study, might I suggest looking into a security guard gig? This was one of the many short term / part time gigs I did in my younger days. You get a night shift somewhere, absolutely nothing happens for hours on end. Lot of college guys, including myself, went this route.
