In the weeks leading up to Capricons 22 & 25, I was getting chest pains because the stress was so bad. Something that helped me a lot was following the old saying "When in danger, when in doubt, run in circles, scream and shout." Seriously, I'd throw my arms in the air, wave them wildly while running in circles, yelling at the top of my lungs. You'd be amazed at how effective it is for relieving stress and how much better you feel after.
