While nightmares and flashbacks are frightening enough, another symptom is worse: agitated (anxiety-laden) depression which can seem never-ending. This feeling of being alone and helpless arouses from infancy, a period when the child is completely dependent on their parents for survival. Gradually, the child's mind creates an image of an all-nurturing parent who, when inevitably absent for periods of time, will always return to supply their needs. This feeling of absolute helplessness and isolation is associated with PTSD symptoms.
