The have "sun" lamps, and people who suffer from seasonal depression can sit for a half hour a day in bright natural full-spectrum light and that seems to do the trick. Other kinds of depression are harder to deal with... basically because it isn't the weepies but the lack of desire to do anything which is the problem. I'm fortunate to have friends who will pull me out of the house by my heels when it gets too bad. (Any activity or change of pace often helps.) Carolly
