As sad as this piece is, there is a certain inspirational quality to it, too. The pain may never fully retreat, but a fortress can certainly be put up to keep it at bay.
This reminds me of something I heard once. If you are consumed by fear or pain - completely overwhelmed - give it five seconds. Let it rage through you and have its way, but when you get to 5, it stops and that's it. Throw everything you have at it and don't let it in anymore.
I hope you are well and all the best to you as ever,
