I went through something sort-of-kind-of similar almost ten years ago. I got a good full-time job as a programmer/sysadmin before I was even out of high school, moved across the country and got another job with a large corporation where I became one of their lead techs while working on a few other projects for them. I made more money than I knew what to do with and I should have been happy.
But, I kept getting more and more unhappy instead, and finally decided that I needed to do something really different. I decided that I'd had it too easy, so I was going to set out to make life really hard for a while. (I had no idea what I was getting myself into. All the same, I'd do it all over again even if I knew.)
Anyway, I left the computer industry entirely, moved back across country, tried to become a forest service ranger and ended up becoming a climbing instructor after having a few other odd jobs. I was broke, but happy. I returned to the tech industry several years later and now I'm much more comfortable with it and well-balanced.
You have resources and you sound like you're a lot smarter than I was, so you could probably do something similar without the kind of hardships I experienced. If you're not sure of what you want to do next, then go out and experience the world in a completely different way until you find the next thing you want to do. Go and do things you've never done before, then come back and start another company.
The main thing with this advice is just to make sure that you don't do nothing -- make sure you keep pushing yourself to do something every day. But I doubt that you'll really have that problem from the sounds of it.
