I'm looking for all things EMDR related.

I've been in therapy since December and have been making steady progress. Most of my past therapy has been CBT, but this time I'm doing psychodynamic therapy. I adore my therapist and have gotten more out of the last 9 months of therapy than the last several decades put together. I have a certain issue that I haven't been able to make much progress with. We did EMDR around it tonight for the first time and I feel like I've been hit with a bus full of emotions. I had breakthrough after breakthrough but I don't know why. Does anyone have any insight into or experience with EMDR? Thoughts? Feelings? I've been googling it but I can't even think straight right now.
