Just what I need--another phobia

I walked home from the train in a thunderstorm this evening and hyperventilated the whole way. I felt a little silly having to chant "everything's going to be okay" to myself, until I was two blocks from home and the tornado sirens started going off. Then I felt somewhat validated--or would have if I hadn't been running. I'm sure that was quite a sight--7 months pregnant in a dress and gym shoes, sprinting down a busy, flooded street. I made it home okay. Nothing fell on me, and there were no funnel clouds. But after this week, I'm really starting to wish I lived in the desert.
