I have Bipolar II, so I both go through meh bleargh depression everything is the worst... and ZOMG 120% DO DO DO FASTER FASTER FASTER!!!1!

Having experienced nearly every extreme of emotion, I don't know if going at "maximum" capacity would be all that healthy. Not that depression is, either, but I've found measuring one's "output" doesn't lead to happiness, either. You have value more than what you can do or potentially do.

God be with you in your struggles.
