I'm pretty sure I may have discovered an alternative to Prozac. If this gets out the pharmaceutical companies might have me assassinated.
Just put a t-shirt in the dryer by itself for about 10 minutes, then as soon as the dryer cycle finishes open the door as fast as possible and put the t-shirt on. As long as the normal climate where you live isn't above ten million degrees celsius every day, a warm t-shirt will make you happy no matter what. It's even better in the winter. Spend the entire day in your boxers shivering and complaining about the heat, then when you are about to go to bed put on a freshly warmed shirt and jump into bed. If you're still either cold or cranky after that, well then go fuck yourself because you're hopeless.
