I'm sick of this

So I called into work sick today, and I'm feeling kind of guilty. Ned can call in anytime with any reason, and no one at his work bats an eye-- it's really no big deal. It seems like I always find some reason to get mad at him on those mornings. I suppose, subconsciously, I'm jealous. When someone calls in at my work it creates a whirlwind of frenzy and confusion. Who will take this person's kids? Can we pull staff from another classroom? Maybe I can take their kids- no wait that'll give me a triple! Should we cancel a session?? It's one huge hectic mess. I basically can't call in unless there is a really, really good reason. Which brings me back to the guilty part... I've been under the weather for about a week, and last night I was up all night feeling really bad, but then this morning I'm back to being just under the weather again. I mean, I can justify it in my head, but I can't help feeling a little bad.
