Yeah, similar mate.
My therapist works towards it. She gets me to do some writing about my trauma's. Things I can remember without getting too far into it. Then when I visit, she asks me to read through it to get my stress levels up. That's how they did it with Brain Spot Therapy. The good thing about Brain Spot Therapy is that you don't have to go all the way into your trauma.
You know how you find yourself staring at a certain spot sometimes, nothing in particular, just a blank. Well, they have associated that with like an 'Eye Cue'. You can actually do it yourself. You can actually find a spot that makes you angry, one that makes you sad, and of course, one for relaxing. Ask your therapist mate.
Sometimes, you are just not ready. But then again, its the brains natural reaction to not want to go there. But the more you go there, the more numb it becomes.
I will reiterate, you will never ever lose that horrific moment, but it will become a memory, like your 21st, or a child's birthday.
I always tell people to watch 'Band of Brothers'. I like watching the actual veterans when they are recalling a battle that happened 40 years ago. You can see the raw emotion of PTSD. Where some of them can talk about it like nothing happened.
