Ugh...I totally relate. That's not where I am right now, but that's exactly (almost verbatim!) how I feel when I'm 'settled' into a depressive episode. And I know cognitively that I've felt better, and probably will again, but I can't remember what that feels like. It seems like it's always been that dead/empty sort of feeling and always will be. I'm nervous I'm headed that direction right now. My therapist said I should try to remember that because this is cyclical, my body is just trying to recover from when I'm on the upside, and to be with this down side compassionately. Let myself take the break I need, and not beat myself up over it. Not focus on how I think it should be, how I should feel, and just let myself be how I am and feel how I feel. I can't ever seem to do that once I'm down, though. And it's hard to just let myself be when I also have responsibilities and can't just sit there for months at a time (I think my last episode was around 8 months or so - can't quite remember). Whatever manages motivation is shut down. Whatever manages memory is shut down. Whatever helps me to realize that standing up from the couch is not, in fact, the hardest thing in the world to do...is shut down.

Not inspiring, I realize, but just wanted you to know that you're not alone in that feeling. I hope it goes away for you, and sooner rather than later. Can you email your pdoc? Maybe that will feel like less of a chore, since you aren't really expected to converse, then?
