"...Feeling Misunderstood Hurts, Literally:
When your sister doesn't get why it's so important that she attend your husband's party, it hurts--physically and emotionally. Researchers found that feeling misunderstood makes people less tolerant of physical pain. Those who felt they were perceived accurately during conversations with strangers were able to keep their hands in ice water longer (a common test of pain tolerance) than those who didn't feel understood. That's why being with someone who really gets you can make you feel ready to conquer the world."
It's just one of those "Did You Know..." one-pagers, but I got really excited because this is a thing! It may mean that I will hurt for the rest of my life, but now I understand. It's nice to be a little validated about your feelings.
