I experienced this, to some degree, a few years ago; I was mid-thirties at the time. I bought a motorhome and started driving. I traveled for about four years; my business and my income suffered for it, but my mental health improved. I started another non-tech company, a worker-owned cooperative, and mostly failed at it (it never made much money, but I had fun, helped make some really cool stuff happen in my community, and learned some things). Somewhere along the way I started to regain some of my joy in technology (mostly I realized how much magic I have at my disposal compared to most people who can't program, can't build/deploy/administer servers, etc.), and have begun several new projects and begun to refocus on my primary project/business in a manner I haven't been able to do for a while. I moved into a regular house a year ago, but decided I didn't like it, so two days ago I bought an old Avion travel trailer (one of the shiny silver classic kind) and will be moving the rest of my stuff into it tomorrow. I'll be hitting the road again...but, will do so in a way that enables me to be connected to tech more deeply, rather than almost completely disconnected. I'll spend some time in Silicon Valley, will catch several relevant Open Source conferences, etc. I'm not telling you to buy an RV and travel from Alaska to southern Mexico for four years. But, it worked for me. Maybe a major change really is what you need. If you've been reasonably successful with your tech work, you probably have some flexibility in what you do, at least for a little while. Make use of it. I wound up quite broke in the process of all this, so maybe don't go as far off the reservation as I did; that may be part of my impetus for getting back into tech with such gusto...money comes so much more easily for tech work than any other work I've ever done (maybe partially because I'm so much better at it than any other work I've ever done).
