Cheapest thing on earth, find a library and read your way through it. Bonus, you get free access to local newspapers. Not every company advertises on the internet, especially some of the smaller operations so you can go through the classifieds for free. Also consider hooking up with a temp agency, even if they only find you the odd job every few weeks it's better than nothing. There's a lot of seasonal jobs available in large retail organizations, don't look for advertisements, actually go there or to their website and physically put in an application. Fair warning, lousy hours and know if you get hired you get a pink slip Christmas Eve but still a buck's a buck.
The big thing is find SOMETHING PRODUCTIVE to do daily, set a goal, get it done, doesn't matter how small. One job application a day, read 100 pages of a new author, clean out a closet, anything. And yes, it's hard as heck to motivate yourself but nobody else can do it for you (which is why working from home is so hard, nothing to keep you on track, the need to set and stay focused on your own goals and self monitor. I did it for nine years, I know how hard it is).
