I have felt this same way so many times. The relief of getting back to your domain (your seat) and knowing you don't have to do that for a while is amazing. Then you feel it...that inconveniently timed urge to pee...and it all starts again.
People who are spiritually minded tend to suffer from anxiety & depression more. But this is because their eyes are open to a world that is in need of repair. They literally have an increased ability to feel the emotions of people around them.
