How do you get over the "mean reds"?

Holly Golightly, in Breakfast at Tiffanys, speaks of a mood called “the mean reds” – a more aggressive form of the blues. I’m feeling that way today for a number of reasons. Have you ever had them? What do you do to get out of/live through them? (I first threw this out without details as a playful question but it was modded. Hence, the prosaic details.)
