Boy, do I understand! My mood can change in an instant, for no apparent reason. H thinks there has to be something that triggers it, but usually there isn't--just constant thinking about different aspects of the affair.<P>On the practical side, we have been walking together 2 miles 4-5 times a week. The exercise has helped, relieves stress, plus this gives us some additional time together. Though I was somewhat skeptical, I finally gave St. John's Wort a try. It has helped a lot, without some of the side effects of antidepressants. But consult your doctor or counselor for what would be best for you.<P>Good luck! You're not alone--some comfort, huh?
