Absolutely! I worked extensively on a site called Elance.com. You can post a profile of yourself and bid on jobs. There is a free membership that provides you with a certain number of bids you can make and there is a paid membership that is very low cost. I obtained a GREAT deal of work through Elance until I became disabled. It is a safe, verified place to get contract work. They use an escrow system for payment so you are protected. It's a great site. Companies and individuals post jobs they need completed and you bid on them stating your rate of pay, your experience, etc. They then choose their contractor. There are a bunch of different job categories from writing to website creation. You might want to check it out.
There are other sites that are similar, but I found Elance to be the most user friendly. A lot of people make a good living with Elance.
Also - you might want to go to Careerbuilder.com and run a search on "telecommute". A LOT of companies are realizing the value in having people work from home. It reduces their overhead and provide greater flexibility for their employees. It also reduces the amount of days people take off. So - run a variety of search with different search terms. Even use "home", "work from home", things like that. Ignore any that require investments - they are not worth it. Look for bona fide companies looking for telecommuters. It is becoming more and more common as the years go on.
Also, sometimes companies post jobs and do not list them as a telecommuting opportunity, BUT you can always propose to them that telecommuting would benefit both of you. I have done that successfully in the past.
I would suggest Elance to get started. When I was working, I was able to make about $30,000 per year working through Elance. It is legitimate and safe.
I am sorry to hear about your bad news. Hope things are getting better for you. Hang in there.
