My divorce took a long time, and I think that time was a buffer for my emotions because I had processed so much by then that the actual paper arriving in the mail was just a bittersweet moment (the day after Christmas no less).
A fast track D is much more traumatizing, you are still processing the main event as well as the evaporation of your life as you knew it.
The good thing is that a new life awaits.
Big hugs. It gets better.
