More will be revealed with the DSM V in 2012... where it will all become official for insurance purposes... but it is still recognised now by the mental health field as a legitimate diagnosis.
The psychologist that I saw at the time specializes in ptsd in general and has seen people with all types of traumas, cptsd is the diagnosis she gave me *shrug*
I personally feel that the separation has to do with major childhood trauma or ongoing trauma in relation to just an event that happened at a point in someones life, like a car accident.
I also suffered a major identity crisis when I was 16 and still continue to have a loss of sense of self due to people in my life, mostly my parents, trying to control what I do, what I say, and how I behave or feel, and not letting me be myself. My parents put a lot of emphisis on grades in school, because I didn't get good grades I was not allowed to go out and have a social life. I'm met with the self doubting questions of 'who am I?' and 'What planet do I live on?' I have a difficult time getting people to take me seriously or acknowledge what I am saying, and especially have a hard time getting people to take my NO as a no. Most of the time I feel I'm speaking a language that doesn't exist on earth.
Perhaps this might give insight to cptsd and what I'm experiencing as someone who has it.
