Many years 911 here, BTDT.
IMHO, one of my former commanders seemed to have the best way to describe his process. I adopted it and it works well, for me....
Imagine a house in your head. Inside are the normal rooms and some are bedrooms, there are closets inside these bedrooms. On the upper shelf of one of these closets are a bunch of small boxes, all types of boxes. Some are shoe boxes, some jewelry or watch boxes. Some are wrapped in fancy paper and some are bare cardboard.
Each of these boxes contain a separate demon, representative of each of the awful calls that you ran. They are made up of the pain, emotional torment and trauma that was a part of that call. Each box hold the possibility of eating a pistol.
Every once in a while, you must go into that room, pick a box and take it down.....then open it up and make your peace with this demon. Once you're done, you close it up and put it back in the closet, on the shelf.
This process makes the most sense to me......and they have worked for me.
Two times so far, and recently as a few days ago some trigger causes me to find myself back in the throes of the original call that caused all of the issues. I was walking the dog with my wife and we had just returned to the truck. I checked my phone and saw a post about a call from 3 years ago. I was back on this call....with all if the smells, sights and sounds. I was in the parking lot of the park and also along side the road on that call. I broke down.....I was cratered.
I talked it out with the wife and a buddy who was there.
PTSD is real and we are all afflicted. Get some help, talk it out.
Give me an IM if you need some help.
You are not alone.
