PTSD from an affair?

Below is the criteria for Post Traumatic Stress Disorder, if you remove the so called need for the death or serious injury you would find that many people who have been through an affair in their marriage suffer most of the symptoms.

I have highlighted the ones that apply to me.  But this is not news to me that PTSD is something I might suffer from.  I had a counselor point it out to me before researching more about it. One thing that I hope others get from this post is that AN AFFAIR, whether sexual or emotional, or whether it lasted 1 month or 5 years, CAUSES TRAUMA.  It is real.  And I feel the pain as if it were yesterday, even though I am going on a year since finding out.  I feel broken and not sure that I'll ever be fully put back together again. I am sorry for anyone who has gone through an affair and I hope you know you are not alone and that maybe it will help you to know that if you are suffering any of the symptoms below, that it is a real disorder and not that you are going crazy. ;)
