You’ve felt this way before, but you thought it couldn’t possibly happen again. The fatigue hits you like a tidal wave as you roll out of bed. Your head begins to pound harder with each step on your way to the shower. Your muscles cry out for forgiveness, even after you pummel them with hot water and fight the urge to return to bed. You shake your head, forgetting for a split second how much it hurts, trying to clear the cobwebs and remember what you need to do today.
