Who, kyeruu? He's some kind of teacher, actually...
Anyways, it sounds to me like the way I felt when I went through my "There is nothing" phase. Yeah, it's just a phase. I suggest buying a DVD of a childhood favorite show, something to find your "roots", I guess. Start over. If your personalty broke, then build a new one! If you liked your old one, then build the new one off what built the original!
