The natural progression of bipolar disorder:

Depression > deep depression > despondency > recovery > fogginess > exhaustion > functionality > public panic attacks > Oreos

How to survive a bipolar crash:

1. Ride it out. Sleep it off. Which I've been doing since Sunday afternoon.
2. Walk through a spider web and do the frantic spider-web dance. Which I did this morning. Bipolar depression is no match for the absolute mathematical certainty that there's a giant man-eating spider somewhere on your body. Or crawling into your shirt. Or down your underpants.

There's no real way to "fix" bipolar depression

You just have to ride it out. But sitting around with your parents, eating a malt made by your dad and listening to Widor's organ Toccata sure collectively go a long way toward making you better.
