A reader asks:

┬áRegardless of the season, on rainy and cloudy days I feel so depressed that I often find life too hard to live. And on a bright winter day I can feel fine. If I do not have SAD, then what is the name of my “light-deprivation-oriented” depression, and how can I treat it?

Answer:

You have given it a good name! Even patients with SAD show a similar reaction of mood and energy slumps on rainy and cloudy days in the summer. And you might take a hint from them: they will pull their light boxes out of the closet, a day at a time, to counteract such transient dips.
