First, let us be clear. You have to realize that you are incredibly fortunate to be able to work in this industry and produce something of value that business rely on (software). As you have realized, software/technology aren't going anywhere. They are becoming part of everything, even in the real world. Before he revealed himself as a true one percenter, Marc Andreessen wrote a nice essay (

Many years ago, like you, I put all my eggs into one basket. My tech job. There is definitely a diminishing rate of return with putting your all into a job, especially as a coder monkey.
My suggestion, as I've suggested elsewhere (see also https://news.ycombinator.com/item?id=14684307), is that you need to diversify out of tech. Stop putting so much energy and time into being in the industry and keeping up with the industry.
While the week off to do some things around the house is a good start, I think you need to take "a vacation" more regularly. By that, I mean to approach something new with the attitude that you are on vacation. Vacation is sometimes more about attitude than latitude (but latitude definitely does help).
There is a saying that goes something along the lines of: never let your hobby become your avocation. I hope that you can find a hobby or two that will never (likely) become something that has deadlines or monetary payment attached.
It seems that taking the week off has helped you realize some things about what you want to do. For a lot of people: work doesn't necessarily make you happy but it gives you the means to do something that makes you happy. You don't have to love your job. And you don't have to hate you job. Extremes make good drama but the reality isn't so black and white. Please don't quit your job. At least ask for a sabbatical first (be prepared to imply that you will quit if you don't get one, as this is the only way you can get a sabbatical). And please don't quit the industry without first exploring what possibly you can do the replace the income that supports the lifestyle that you are accustomed to. You will likely find that there isn't really much out there, especially if you like human to computer interaction more than human to human interaction.
I hope you find something that helps you get away from your screen more. Ideally, every single day (like learning how to draw or garden). I believe, the solution for burn out, for someone like you, is to find something else (a hobby or two) to do so you can burn off that ever-present internal desire to do something.
Maybe you have a hidden talent that people can connect with. Put videos on YouTube.
Good luck!
