There are a few things I have kept from my T. One of which I almost feel like if I ever openly admit it, I loose my connection to humanity. My trauma lasted over two years and it consumed me. It was a situation that I had to emotionally detach to survive. From the time I woke to the time I went to sleep (if I could) I had to be on guard.
I have found in my 10 months of therapy that there is a lot my mind had blocked. I find I downgrade events by comparing my experience to others that were there with me. I'm sure as the cats continue to come out of the bag, I will divulge more to my T. Of the things I keep from her, I think I keep them from myself. With the exception of one event which when I think of it, it always is in the third person.
