What do you do when you're devastated?

It’s just a feeling—maybe related to events or maybe not. But some idea or other takes over your mind and won’t let go. Your body starts to hurt all over and your head feels like someone is pumping compressed air in it. Your stomach feels like it’s eating itself inside out. Your mind can’t stop going over and over whatever story it tells itself.

Can you just control things with, say, mindfulness practices? Do you just have to endure the long dark night of the tortured soul? What if you have no friends you can talk to? What gives you the strength to endure?

I try to live up to my name. Wun day at a time.
