Anxiety Attacks.

[Jughead P. Jones]

There's been a lot of great responses so far, so I don't really have anything else to add.

But, one thing I usually do when I feel anxious, or angry, or just plain stressed out, is put on some of the most upbeat music that I can find (it could be anything from The Killers to...ahem...Jessica Simpson), and just jump around, work up a sweat and let the music drown out your anxiety. It works for me, because I usually move so much, I flop down on a nearby chair or bed and veg out in a calm state.
