honestly, your best bet is to look for a job with benefits. and yes, i do realize that this is easier said than done and that job opportunities are especially limited right now, but the simple fact of the matter is that people with progressive disability absolutely need crucial accommodations such as health insurance, paid sick leave, and preferably disability insurance. sadly, it's been my observation that the medical profession often doesn't encourage CFers to pursue these types of jobs (or the education often needed to obtain them) because they claim such work will be "taxing" on our health. i disagree. in my experience most jobs are taxing and stressful in their own way. knowing that you are fully covered by benefits and have the option to go into the hospital without losing everything is actually a huge RELIEF, and most professional employers are surprisingly conscientious about their workers' health needs. (most, of course, does not mean all.)
i don't know what your particular field or trade is right now, but there are companies out there known for giving great benefits to their employees (starbucks pops to mind off the top of my head for their health plan -- which includes even part-time employees -- but i'm sure there are others). make that a priority when seeking work (assuming you are looking for a job). and some people will probably disagree with me on this point, but once you have a job offer my advice would be to be as open as possible about your health needs upfront. it may be possible for you to work out a way to minimize your unpaid time off, but you can only do that if you are working WITH your employer.
as for other ways to make money -- um, win the lotto? <img src="i/expressions/face-icon-small-wink.gif" border="0"> okay, just kidding. a more practical solution might be to look into discount or assistance programs to help you with some of your bills. there may be other ways you can make some extra cash, such as housesitting for people who are out of town for short periods or other odd jobs. i know some people on this and other sites have had success by making craft-like items and selling them on etsy (or whatever that site is called).
hope that helps. sorry for the tangent, but i get a little riled up on the subject of jobs and CF.
