Disconnect- sorry I couldn't get back to you sooner.
Do you do desensitization exercises in EMDR? It's like a fast alternating bilateral stimulation while you simply focus on the most distressing feelings without trying to resolve anything. You do it for about 15-30 seconds, take a break, and then return to the original distress. You repeat this about 4 times, take a break, and then do another group of 4 repetitions. At the beginning you define the distress explicitly and rate your SUDS. Then after 1 or 2 groups of repetitions you rate your SUDS again, and repeat the process until you feel significant relief. You may get insights about the distress during this de-escalation exercise, but the idea is to only focus on repeated imaginal exposure until it diminishes, not to delve deep into the trauma like you would in a session with a practitioner.
I first used alternating audio tones w/headphones to create the bilateral stimulation, but now I do eye movement on my own. I sight out two things in my visual field that represent significant differences left-to-right, so that if I can see one, I can't see the other. Then I feel I'm getting a broad enough visual sweep to be engaging the visual bilateral stimulation.
Please talk with your EMDR practitioner about the appropriateness of trying such exercises at home. They should not increase your distress or heighten the range of triggering stimuli, but each person reacts differently to EMDR, especially depending on the length of their traumatic experiences.
I'm really going through issues similar to yours with EMDR. Although I was in EMDR for prolonged rape traumas and sexual abuse, I could talk about that. If I had to talk about what my childhood was like, even the most seemingly benign senses of being "misunderstood", I would fall apart. I kind of "black boxed" that era of trauma, but have been approaching it a bit more in EMDR recently- it is still evoking very difficult feelings between sessions, but the desensitization exercises help.
