Well, you cry it out. You speak it, you shout it or you whisper it. You do what you can to take it out of your bones.
You let go.
Then, you forgive.
And you’ll repeat, everyday from then on: “it’s going, it’s going, it’s going”. And one day it will be. Gone. Forever!
It might take a day or a month or a year; but it will be gone!
