Honestly if I were you I'd probably go for a long camping trip, like for a week or two. Or failing that, a vacation to some natural beautiful place. Then cut down your hours. 40 hours a week is fine, and if someone tells you otherwise then explain to them that you're getting burned out and they'll get better productivity out of you if you work fewer hours. Other than that, you need exercise, lots of natural light, a good diet, and lots of socialization opportunities.
