It happened to me today. I was at a Therapy session and was talking about my abuse in very "matter of fact" manner. My therapist asked me if I felt any emotion, and I honestly had to tell him I didn't. He explained that not feeling the emotions connected to the CSA is a defense mechanism we develop to protect ourselves.
I have done this for years. When I got married, I told my wife that I just did not have emotions. I believed that and of course she pretended that she agreed. However, this is beginning to "break up" now. I'm getting so that I feel lots of emotion. It may seem to some as though I'm moving backwards in my healing journey.
I recently attended the movie: Heaven Is For Real
. I wept through most of that movie. Yes, I had a near-death experience when I was tortured. The movie brought me to re-experience that, in a good way. I'm glad I saw it.
