i can't see where i'm going

I just had two days off of work. I did pretty much nothing, except for scrubbing my floors. The laundry is still unfolded and the dishes are still in my sink. I never got around to straightening up my bedroom. Over the past two days I've been increasingly enveloped by a fog of apathy and right now, of course, I just don't care. The thing that's unsettling to me, though, is that breaking through my indifference is a slightly sickening tension that I feel in the pit of my belly. The only phrase that keeps popping into my head to describe it accurately is 'impending doom'.
