Heres one link I found, but there are several of them if you look up Coping techniques for PTSD symptoms.

Coping with Traumatic Stress Reactions - NATIONAL CENTER for PTSD

(((rep97)), I struggled so much for a while, so I know how challenging it can be.

One day I had all I could do to just get to my therapist's office and by the time I got there I was so bad with "anxiety".

Well, he told me to "observe' how I felt and how my body felt and then he told me to "close my eyes". He told me to picture a big black board like the ones I saw in school. He told me to look for a shelf and pick up a piece of chalk and then write the number 10 on the chalk board. He told me to look on the shelf and pick up an eraser and slowly erase the number 10 and write the number 9 and then erase that too and he talked me down until I had erased the number 1. Then he had me open my eyes and I did "feel better" and "more calm". He explained to me that what I had done was "distract my brain into doing something calm and that signaled my brain to stop producing cortisol which is why we get so full of anxiety and often unknowingly make it worse by feeding into it, rather then doing something "CALM" so we stop producing it and begin to relax.

You can use that technique yourself when you are struggling, you can even decide to draw pictures on the chalk board too. It is all about sending your brain messages that say, "no emergency or need to keep producing cortisol" to get ready for flight or fight.
