Anxiety loves company
Somehow, at least in our culture, we find relief when others are anxious too.
So we spread our anxiety, stoking it in other people, looking for solace in the fear in their eyes.
And thanks to the media, to the microphone we each have, to our hyper-connected culture, it's easier than ever to spread our anxiety if we choose. And when someone who seeks power offers to hear our anxiety in exchange for attention or a vote, it gets even worse.
It's worth noting that there's no correlation between the real world and anxiety. In fact, it's probably the opposite--when times are good, people with a lot to lose start to get that itch.
Absorb the anxiety if you wish, spread it if you must, but understand that it's an invention, and it's optional.
