I've been in the same boat as you very recently (top client unexpectedly had to let me go because of low budget, when I was confident it would be fine through the early part of 2016). And I quite understand struggling to pay rent all of a sudden. Not fun! All I can say is, it gets better! Network like crazy, reach out to everyone you know: old clients, former coworkers, even people who offer the same services you do. You might be able to pick up work they're overloaded with, or talk to a past client at just the right time when they're ready to do another project. Also as other people have said, there are great job boards out there (WeWorkRemotely, etc.). Another thing you can try doing is blogging about some of the work you've done, problems you've solved, etc. -- never hurts to include content marketing in your "personal brand" efforts.
