Just had another EMDR session, and made progress this time. Held the image and feelings in my head, and processed it through and had several changes in feeling in both body and mind and got breakthroughs. By the end of the session I could hold the image in my head and didn’t have the associated feelings. It felt pretty good. This holds promise.
I’m going to be vigilant for repercussions — this may not be the end of it, there may still be fallout from it, but at least I was able to go through it once and come out the other side. This bodes well for the process.
