Dude, just play something else, watch tv, read, exercise, socialize, study (but actually study and learn something, it's fun), travel (if you can afford this, traveling is a brilliant way to disconnect and then come back to things you love), and listen to music too, but ACTIVELY LISTEN. Don't just play it on the background. Put on headphones or fire up a nice sound system and do nothing but listen to the music you love.

All of these things actually augment my love for my passions, hobbies, and pastimes. I can always listen to my favorite band, Rush, because I'm always exploring new musical avenues, for example. So if you're feeling burnout it's really simple. Put the game down and explore other things.
