I was up most of the night with another severe panic attack, which involved a lot of physical discomfort in addition to the mental kookiness.
Mark stayed up with me as long as he could, but when it became apparent that things were not going to settle down, I dispatched him off to bed in Maxwell's room, since one of us had to be sane enough to parent in the morning.
I finished off a lackluster novel, the clothes on their backs- thank goodness it was a library read, and not something I paid for. It was very superficial, although the subject was of interest to me. It worked well enough for something to read while you think the world might be ending and you don't want too much distraction.
