Sad - depends on the level. Lie in bed with a quilt over my head, facing the wall and shaking at the worst. A lot of ruminating about stuff no-one cares about.
Angry - doesn't happen. Wish it did more. Might show some spirit.
Ashamed - isolate myself.

Other emotion I get is a need to do drastic things. A reckless, wild streak. Not sure what triggers that though - probably boredom.
