Oog. I know that malaise. It's annoying enough when it happens to your gaming habits, but when it starts trickling out to other things, I think it's a sign that you either need a mental vacation, or that you need to find an angle on something that interests and excites you so that you can do something and actually enjoy yourself. I don't know, that's the best I can come up with, I've wrestled with this myself and still don't have a set answer.
