This is a great point. Pursue other interests for the time being; don't necessarily stop gaming altogether though. I had a few gaming ruts in my life and around the same time I was in grad school.
Something a professor had said to the class about writing a thesis paper can apply to many things in life: "When you find yourself enjoying what you are doing, stop for the day while you are still enjoying it because you'll be excited to get back to it next time. If you stop working on something when you're forcing yourself to do it, you'll have a much harder time being motivated to continue."
It's not very profound, but I related it to the gaming rut I was in at the time but it helped me bounce back.
