Depression & SAD link

This is one of the best discussions of the effects of depression and SAD that I've seen in a long time. For those of you I haven't discussed these things with, I basically get the same thing as the OP describes (and them amplifies on in comments; the comments there are good and useful): depression - which is not at all the same thing as unhappiness - most of the time, and an extra layer of it comes along with the cold and the gloom.
