I definitely had an enemy with me every day. I too used CBT, EMDR, lots of talking, writing, and crying, I now have many symptom free days. It is not gone; it just gradually lost its power over me. Now I see it as a part of my core primitive mind that tries to protect me from something bad happening again. Every reaction is simply a thought or emotion to be experienced and let flow through.
When I saw IT as my enemy I think I was creating a sense of separateness, giving it an identity. It was something in me or something attacking me. The more I pushed it away the stronger it became. In reality it has always been just a part of me and could not be pushed away. The good, the bad, and the ugly ideas are all mine, and there is room in there for all of them. I have learned to love ME, even the ugly parts.
