You may want to look in to the disability options available in your country, depending on the reasons you feel unable to work. Alternately, you might try experimenting with a job if you haven't already - you might find it more bearable than expected. Nanani's suggestion of alternate employment options are also probably worth looking in to.

Figure out why you don't want to work, and then see what options exist that are compatible with that, basically. A lot of my friends don't have jobs, and a number of them suffer in ways that make future employment fairly unlikely. There are ways to live with this :)
