When I'm angry, I listen to Simpsons songs. "We Put the Spring in Springfield," "Happy Just the Way We Are," "Underwater Wonderland," and any of Lurleen Lumpkin's songs most especially.

When I'm sad, or if I'm angry with my mother specifically, I've found that watching the film Penelope really helps. Tangled, too.

The A Softer World comics help when I'm sad too.
Honestly anything that's familiar is a comfort to me.
