Worst I hurt myself: Older, much larger cousin broke my leg by landing on it in a bouncy castle.
Injury that pissed me off the most: At 13, I loved jiujitsu and rock climbing above all else. At my last jiujitsu class before going to California to, among other things, go bouldering in Joshua Tree, I sliced my heel badly on the metal bottom of the dojo door that had about an inch and a half of clearance from the floor.
Shoes in general, let alone those super-tight climbing shoes, were out of the question for two weeks. I’m still mad. Of all the ways I could’ve got hurt, it was the fucking door on the way out that took me down.
Count from 1 to 10, then 10 to 1. With each number, relax your body a little more. When the mind strays, bring it back to counting. Repeat until unconscious.
If that isn’t working at all, get up, go to another room, play soft music at low volume on headphones, and depending on the circumstances read a book, jot stuff down, or just contemplate stuff. Chill until sleepy, then either go back to bed or just curl up where you are.
