Hey there. Sounds like you have been pretty frustrated in finding a good therapist. I completely get that; I was so lucky to have stumbled on one who happened to have some training in working with cults. I am currently studying for my degree as a counsellor. I am NOT certified to provide therapy at this point (I have not yet gotten my master's) so please take what I'm saying with the spirit in which it's offered...just educating...my last paper, ironically, was on cults and mind control. I plan to have a pretty narrow focus simply because of "been there done that" (raised as a JW) and b/c there are simply not enough counsellors in this field.
Having said this...PTSD is one of those terms that is often mis-used. In order to actually diagnose it, there are several criteria that must be met. Here is a link: http://www.mental-health-today.com/ptsd/dsm.htm Most counsellors would be reluctant to diagnose PTSD based on the majority of experiences most ex-JWs have. In no way am I trivializing the pain, grief, and trauma most of have gone through. I'm simply saying that unless there was trauma like physical or sexual abuse associated with a specific JW experience, most ex-JWs would not qualify for this specific diagnosis. For example, I recently worked with a gentleman who has PTSD; he was subjected to horrific child abuse (physical and sexual). In the military he was special forces and has described to me actions that were just...well...more than any one person should ever have to endure. He experienced incredible trauma and will disassociate completely and be unaware of his actions, conversations, etc. etc.
The DSM-III had disassociation as a possible diagnosis resulting from the mind control exercised by cults. However, the research that was based upon was found to be flawed. For that and other reasons, mind control as a reason for diassociation was removed in the DSM-IV. (DSM-III and IV are the manuals used by psychologists and psychiatrists to diagnose disorders).
So yes. I agree that the psychiatric profession needs more qualified counsellors to work with survivors of cults. I'm sorry you are going through a hard time - I don't know any details, of course, but it is obvious you are struggling. If I can help, feel free to PM me.
