I think I do have some issues with SAD. I don't think it sends me into episodes per say, but it mimicks mild depression. I feel tired and blah and don't want to do anything. It's the gray skies and dreariness. Rainy days get to me in any season. So during the times of year where the skies are constantly cloudy, I have problems. Fall and winter, particularly. One of these days maybe I'll try a light box.
