I tried EMDR but my therapist did not prepare me in any way and certainly not in the way that pattijane suggests.

I did ok in spite of it for a time. I processed some difficult memories and it had the desired effect of those particular emotional (beliefs?) having less power and intensity. I was abused severely from age 2 to 14 so there is so much..I finally stopped going because it was too hard. I prefer a gentler route for now but may do it again.

I would say it was worth it and would work especially well if there is one particular trauma you would want to address. I would use someone reputable.
