I suspect that Jacq10 is right. I know that when people are depressed it can either be with the leaden, dead to the world variety or with the anxious, restless variety. Both can be killers, but if you have only had one type, you don't know how one can be the other. I've had both as part of my symtom profile, so I can understand how deadeningly exhausting depression can be if you've got the melancholoc variety. I think Peg was honestly trying to understand, not lecture.
By the way, I routinely go through a couple of days every few months-even when I am not technically depressed - doing nothing but sleeping. Holding the BD to somewhat manageable levels is REALLY draining
