Thanks, Mary - I don't want to sound disparaging, but...

Those who feel 'down' because of outside influences are the lucky ones - the way out of their depression is relatively easy.

Those of us whose depression comes from within are victims of our own capricious minds, and external influences often are totally ineffectual.

Sorry to cast a damper, but I know. I've just been there (I hope it's 'been' - maybe I'm still there, and won't find out for a few days...).
