Sometimes I'm Such a Freak

So, I've been worrying and worrying that I'm not doing a good job here at New Company. I mean, to the point of actual depression and loss of sleep, etc. Well, today I received my manager's review that is meant to go with the small raise I got last month and I was shocked to find that it was almost all completely positive. Ironically, the only thing about it that could be taken as a negative is that I need to have more confidence (now, where I have I heard that before?) I just really, really need to learn how to relax.
