My chest is heaving. The air I rapidly suck into my lungs does not seem to be adequate as I immediately gasp for another breath. My heart is pounding, trying to escape the confines of the sternum that lies over it. The waves of nausea are somewhat overshadowed by a brewing headache. To put it bluntly, I feel like crap. My eyes gaze towards the clock on the wall and to my dismay it’s only 5:40 AM. Twenty more minutes of hell stand between me and relief. And I can’t help question for a moment why am I here again?
