I don't have CPTSD. However, I have done EMDR and will be starting EMDR again in late November.

I think EMDR is a great method of trauma therapy. Where regular trauma therapy is like diving into the ocean of (a) memorie(s) and trying not to drown, EMDR is like sitting at the beach, watching which floats to the surface. No swimming required.
EMDR has helped me a little bit so far. But I'm counting on lots of little bits to add up to something significant.

What I also like about EMDR is that you don't have to tell the T anything you don't want to say or don't want him/her to know.
