In so glad it worked for you. I have heard it has been successful in some. But I have also heard of others who it has retraumitized. One is a client of mine who is a war vet. It really messed him up.
It also runs counter to everything I've learned about trauma and PTSD. Especially when it comes to effective therapies for kids. A fabulous psychiatrist who specializes in treating kids with intense trauma has written books about what works and what is dangerous. He says that traditional talk therapy or anything that purposefully relives or brings up the traumatic experience is supposed to be retraumatizing.
Instead, he provides a sort of calm, natural therapy that allows the kids to bring up or act out abusive situations or traumas without prompting but then flip it so they are the ones in control.
It can take a long, long time.
He worked with the Branch Davidian survivor kids, children raised in extreme physical abuse and isolation and a kid who watched her mom be hogtied, raped and murdered before the little girl had her own throat slit and was left for dead.

I've heard way too much that is bad about EMDR. Just type in "EMDR dangerous" into Google and there's a lot of stuff about it. I would never recommend it as a result even though some people like you have had benefits. It seems like it can work for some - maybe those who are very self-aware and understand their trauma- but can be super dangerous and risky for others. But I'm not a psych so I dont know.
