Okay, so I've had depression my whole life. But this past week or so it's been kicking the shit out of me, I barely feel alive. I just can't get motivated outside of "busy work" I set for myself so I don't get unhealthy, and I can barely muster that. I don't know how to pull myself out of this damned slump; and I don't want it effecting those I love.

What do?
What do you guys do to get yourself out of a slump?

Tl,dr that led up to this: a really bad episode of ptsd, followed by agoraphobia triggering on because of that, followed by holiday induced home-sickness.
