One step at a time

Have you ever walked along a precipice?
It's how I walk now, careful not to look down, I'm walking the thin line between sanity and insanity. Or maybe I'm already mad. The voices in my head are back, incessant in the background. I don't know what they're saying but I know I've to carry on, one step at a time. If I fall, there is no one to catch me. Long is the drop, I can see my broken body on the rocks below, but I go on, one foot in front of the other, leaving my bleeding self behind.
