You feel terrible, right? I mean, worse than awful. You feel so bad that you can’t even admit it to yourself, but you’re running around like a chicken with its head cut off searching for a way to make the badness stop, and you’ll try anything, all kinds of shitty strategies, distractions, substances, things you know won’t work, even things that are harmful, because every new blast of emotional badness sounds to you like a klaxon that is screaming in your ear FIX IT FIX IT FIX IT NOW. But the awful feeling isn’t necessarily be a problem to be solved. There might not even be any particular reason for it. Does a person stuck in a blizzard run around trying to find ways to turn off the weather? No, they do not. So just try to relax, and don’t do anything.
Of course, you’ll still feel awful, but that was going to happen anyway.
And if you can somehow get through it without completely freaking out, you might even learn some of the strength and resilience that will genuinely help you in the long term.
