About 15 years ago I quit my job at a consulting company, and the realization that I was happier sick than healthy and working there made me quit. It really liked it at first, but it was a slow burnout, so slow I didn't realize I ended up hating it.

The funny thing is, I recovered in one month, quit, and had the happiest two months after that; but after the fourth month I also realized that I still like doing my job, just not there. It took me three more months to find a new job I liked, meanwhile the initial happiness rush became boredom.

My point is, working with your side projects will improve your skills and stave boredom; and who knows if you'll find you just needed a sabbatical instead of staying at home forever.
