Although it is important to be able to recognise and disclose symptom of physical illnesses or injury, you need to be more careful about revealing psychiatric symptoms. Unless you know that your doctor understands trauma symptoms, including dissociation, you are wise not to reveal too much. Too many medical professionals, including psychiatrists, believe that hearing voices is a sign of schizophrenia, that mood swings mean bipolar disorder which has to be medicated, and that depression requires electro-convulsive therapy if medication does not relieve it sufficiently. The “medical model” simply does not work for dissociation, and many treatments can do more harm than good... You do not have to tell someone everything just because he is she is a doctor. However, if you have a therapist, even a psychiatrist, who does understand, you need to encourage your parts to be honest with that person. Then you can get appropriate help.
It appears that DDNOS is the intentional goal of these abusers, but DID sometimes results from a failure of programming. In DDNOS, the ANP is always present, even when another part is in control of the behavior and feelings.
Fear and anxiety affect decision making in the direction of more caution and risk aversion... Traumatized individuals pay more attention to cues of threat than other experiences, and they interpret ambiguous stimuli and situations as threatening (Eyesenck, 1992), leading to more fear-driven decisions. In people with a dissociative disorder, certain parts are compelled to focus on the perception of danger. Living in trauma-time, these dissociative parts immediately perceive the present as being "just like" the past and "emergency" emotions such as fear, rage, or terror are immediately evoked, which compel impulsive decisions to engage in defensive behaviors (freeze, flight, fight, or collapse). When parts of you are triggered, more rational and grounded parts may be overwhelmed and unable to make effective decisions.
