This cold/general virus thing I've got has been upsetting my sleep, which has in turn made me more irritable.
Also, my lift into work this morning left without me because I was three minutes late. When before I've had to wait twenty minutes for her because there was something on TV she wanted to watch. As I was feeling crappy anyway (see above), I was tempted to just give work a miss. However, I ended up catching the next bus in (which was two hours later...), but not before having a minor breakdown and curled into a ball full-on sobbing (would say I can't remember the last time I did that, but I'm fairly certain it was Sunday 26th April 2009. May have the date wrong).
Oh, and my computer's being slow again. See first point about my irritableness.
