I could see my vision tunneling, the red blood dripping from my finger seeming to grow more vibrant as the black on the edges of my vision closed in. "I...I need to sit down." I whispered, taking two steps and plopping down on the nearest short surface I could find. 
It wasn't that bad.
It wasn't that bad.
Yet, I couldn't stop looking at my finger even as the attendant covered it in Neosporin and gauze, hiding the bloody sight from view.
So. Much. Blood.
I didn't think such a little thing could cause such a reaction in me.
Yet here I was, finding out differently.
