I read here somewhere that it should not be considered if external stress is high as in living condit...
That is where I am now and taking a break from EMDR because what you say is true.
I have been married 30 years to a narcissist and can't get out of it on my own, but through EMDR I realized the abuse from family and childhood through adulthood led me to overlook signs and marry him anyway because all I ever wanted was to have a family and I was already 36. I trusted others who knew him over 20 years and vouched for him and identify him as a church leader.
The EMDR was the only thing that ever made me grow beyond the repeating self condemning voices in my head. Talk therapy has been useless for me.
I just saw a medical research paper titled, essentially, "never use EMDR on childhood PTSD" but it was too hard to focus on it at the time to see their reason. I should look for it again to see if its premise is relevant.
My therapist was very good and I identified with her (including her own unhealthy family), but she wasn't getting therapy herself to my knowledge, and I recognized some things she said that were harmful. She is human. Other therapists are so much worse.
The damage came when she let me keep talking, which I can't control, except I told her several times I don't like to talk about it. I wanted to stick to the effective objective and slower approach of EMDR.
As a result when I left sessions I was extremely upset having been reminded of the pain, which was more intense since I'd finally come to realize the hate, not love, it took to impose it on me and turned me into a willing scapegoat.
I began having accidents and am constantly dissociating and endangering myself other ways. I have alienated myself from others but I have been agoraphobic since age nine or ten. I am trying to stop being so impulsive but it is impossible.
I wouldn't sue her because I can't even do what I need to do on a daily basis, but she helped me and nobody else did, so can't say I would.
As far as my husband goes I stay away from him and ignore him as much as possible, also I learned to fight back but it is sick and would hate to treat others the same way. I have to remember the good things I have.
