I feel unhappy all of a sudden. I'm not sure why. There are a number of little things that could contribute to an overall feeling of malaise, but none of them individually is significant enough to make me feel as lousy as I'm feeling now. They are all relatively trivial things -- a bad skin week, not enough sleep, eating poorly, minor job anxiety, a niggling sense that my boss is not altogether pleased with me, although I can't think of a reason why that would be so -- but somehow they've been enough to bring me from feeling relatively cheerful and optimistic this morning to wanting to go home and curl up in bed and sleep for two or three days. I don't know what it is.

Also the launch of the project I'm managing/co-ordinating is coming up, and I'm feeling a bit nervous about the amount of responsibility that's sitting on my shoulders right now. I'm worried that the launch just won't come off the way it should, that it will be a particularly inauspicious beginning to the whole project, and that that will be a consequence of something I did or failed to do, and that I will look incompetent.

I hate self-doubt.
