Totally second the travel, move to a strange place, do something random like work in events, theatre, a coffee shop, meet new people, get stories. I was in a similar depressed/burnt out situation & moved and it totally rebooted my life. Could also try moving away from CTO to a CEO type role if you want to stay in web/startups without the coding. Loads to learn, plenty of cool people to meet and very intellectually stimulating.
