Horrid mood. No single cause; just lots of straws on this camel's back and an underlying tiredness and frustration with myself, then with others. The "others" part is what comes to mind most easily, but I know better when I stop and take inventory. Tired of everything, and tired of everything being so much work.
Next up is slogging through tidying up the office. It's an absolute pit, and I'm not going to be a lot of good in the way of productivity until I've dealt with some of it.
Can't believe I'm this fed up with a good life and a good job.
