sorry this is a bit late, and apologies if others have mentioned it, but I found that saying it out loud helped for the instances that I have voiced. I also feel strongly that if I could say the rest out loud, it would help a lot...
I did however read the instances from paper when telling my T the details. This made the telling similar to doing EMDR-type stuff because my eyes moved back and forth across the page from left to right. This is similar to the methods of EMDR moving attention from side to side. I think some of my relief came from readign it out loud, and not just telling it. Other abusive experiences that I have talked about in the past (without reading), have not had similar results from telling...
Just something I put together when I realized that it was different reading the instances than it was simply telling them.
