I don't know if this is appropriate (if so, you mods can take it down) but one way I deal with the stress from PTSD is through drawing things of my experiences. Translating some of the intrusive memories to paper.
I was run over by a motor cycle. One of my more intrusive memories is the visual of my hands, covered in my own blood, being held in front of me. I'm an amatuer at best, never taken lessons.
If you have any art, post it here. Maybe we could start an image board. :)
