Sounds cliche but time. Also, hang around with friends.

Thanks rarepepe :)

Wallow around in it for a while. Let it sink in.
And then kick life's ass. Clean your entire house. Something to take your mind off it yknow?

Take a really long shower while playing Hallelujah as loud as you can.
I don't mean really loud. I mean AS LOUD AS YOU CAN
IT DOESN'T EVEN HAVE TO BE THAT SONG JUST SOMETHING UPBEAT
DANCE TO JUSTIN BIEBER IF YOU WANT

You don't.
