I kinda blew it

I'm sitting in class right now, typing this as my students take an exam I wrote. They hate it, and they hate me right now. I guess it's just way, way too hard. I had a fever when I wrote it so actually getting it done as opposed to making it fair and moderately easy was my main concern. But now I feel rather chagrined and i'm slinking down behind the computer monitor right now so that I don't have to make eye contact with any of them.
