Well, the DSM states watching footage can't cause it, actually. "This does not include indirect non-professional exposure through electronic media, television, movies, or pictures."

I read the blog, where she mentioned the importance of seeing a clinician for diagnosis, she doesn't sound like a trauma specialist though offhand: http://www.mariehartwell-walker.com/?page_id=5

Here's more in case you do want to look at the symptoms, too: http://www.ptsd.va.gov/professional/...teria_ptsd.asp

A lot of folks use the PTSD term very broadly, like a catchall, there are other anxiety disorders and such that can fit better, but certainly, the main thing is to get an understanding of what pains you, how it happened, and how to resolve it, so... I hope you find that!
