I suffer from a mood disorder already, It's never been officially diagnosed "Bipolar", but seems to be a mild form. I have highs and lows, but normally not "exessively" extreme. Anyway I live in California, and we are currently having weather that is both overcast and warm. whenever it gets this way, the "high" and "low" seem to come together for a little while. It creates a mood that is both mellow and happy, both of which are rare to me. unfortunately this weather type never seems to last long enough!
