I tried EMDR a few years back (8). I had such a negative experience I said I would never do it again. I was working with an inexperienced therapist who wanted to jump right in (without creating a safe place) and work on my most difficult memories. I ended up needing to be sedated and was in the hospital for a few days. My therapist dropped me and I was left to sort through all the memories and issues on my own. I didn't trust therapy after that.
During this process, I had a clear divide between my inner child and myself, and part of what caused that feeling was because I could not admit what I was feeling and where. I could not admit to myself that I felt tension in my pelvic region, tension that built to straight up arousal. I was so ashamed, and honestly still am. I hate that I feel these things. Then thing is... EMDR or not, the tension is there. EMDR literally helps shrink the amygdala and helps grow the hippocampus back to its intended size ultimately restoring balance. EMDR simply helps you see the tension and process it in a way t hat is much less scary.
I hope you hang in there, and can be honest with your therapist about what you're feeling. It is important to recognize what you're feeling so that you can begin to counteract the shame associated with those feelings.
I don't have all the answers, and I still have a lot to lean and talk about in therapy, but I hope somehow this helps! Best of luck to you in what ever you decide.
