Have you ever heard of EMDR ? Its a form of treatment for ptsd and has been quite successful in many cases.I read a little bit about it at a site called... emdr.com It might be worth checking into.

I hope you are able to find a way to get through this so you can take charge of your life.. I know how it is to be controlled by ptsd.

I do agree that talking about the event does help free us of the hold it has over us. Good Luck!
