I recently heard a disaster survivor talking about "EMDR" to help treat stress after a disaster and found a couple of snippets/websites that I thought you might find helpful if you wanted to start researching it. This particular survivor said:

"While focusing on the event or some part of it you move your eye from right to left repeatively, if not able to do it you can use your finger moving in front of your eyes and have your eyes follow your finger once you can do that (moving eye with out focusing on that) then continue to move eyes and focus on the traumatic event, and any emotions or the place in your body where you feel those emotions and any statement you say to your self usually about the event as you do this usually the image will change or emotions will change just allow that to happen and continue to move your eyes back and forth.

You can stop to rest them for a while and then just refocus on where ever you were before and continue to process, after awhile the emotions should shift and then recede, often the mental images change for a while and then are either not there, or not have the emotions attached to them.  Often are able to think about the original event very differently."

Websites you can use to start research are:
