Blood, blood everywhere and not a drop to...spare?

I came out of a room from doing an EKG and there was a trail of blood, a puddle, and then a longer trail. Some guy fell on stairs and got a huge gash in his head. I got to clean his face and the rest of him from blood while they stitched him up. It was awesome! I never saw a gash so deep in my life, and after that, nothing will make me faint. It was really cool. Tons of blood, and-yeah, I think I'll stop right about here.
Oh, I got screwed over again. 4 nights in a row of evening shifts the second week running.
