You know, I was just coming back to say the same thing. After reading the Wikipedia article, I'm wondering if it was just the same-old same-old stress, but then it suddenly collided with a hypomanic episode. Because I really have worried about my blood pressure this week in particular--it's usually pretty good (back during the cat bite episode, the clinic nurse was surprised that it was so good), so I notice when it gets high. I went back and read over the entries here to see if there was anything in particular that could have triggered it (ah, the usefulness of LJ), and on Tuesday we had the water damage, which might have increased the stress somewhat. And then on Wednesday I started reading Twilight. COINCIDENCE?
