Though not yet an official diagnosis according to the American Psychiatric Association, complex post-traumatic stress disorder (C-PTSD) is being informally recognized as a more severe form of PTSD caused by prolonged trauma. Often, that trauma begins in childhood. Trauma that takes place during a person’s formative years is incredibly damaging. It establishes a sense of normalcy around abuse, creating a harmful pattern that can be extremely difficult to break from–or even recognize. The earlier the trauma begins, the more difficult it becomes for the victim to understand her experience as abnormal.
