It is genetic. Many people have been abused much worse than me and did not develop a dissociative disorder. But most who were abused have some form of mental illness. Some become sociopaths or psychopaths. Some become criminals. Some are gay or have gender identity problems. I believe that schizophrenia has its origins in traumas that occur from newborn to two years old. Those who develop dissociative disorders have a genetic propensity to go into hypnotic or trance like states.
