It's such a hard thing this. Being told your being divorced when it's not your choice.
Honestly, am still struggling. But lately I am starting to turn more focus onto what's best for me. Only half my day now is filled with thoughts of my wife. God this is tough.
I will get through this in time.
Your "miracle" may be becoming actively aware that the sitch with the WAS is OVER, and actually releasing it. It will restore a ton of your mind power and remove a huge distraction. You will be able to get alot done.
Alternatively, make forward progress on things that you are supposed to be responsible for - and remind yourself that the WAS is gone. You will get past it.
