PTSD would explain the not reporting. She wanted to protect her family. She was suffering such trauma, her state of mind was altered. PTSD has many symptoms.

What are PTSD symptoms and signs?
The following three groups of symptom criteria are required to assign the diagnosis of PTSD:
•Recurrent re-experiencing of the trauma (for example, troublesome memories, flashbacks that are usually caused by reminders of the traumatic events, recurring nightmares about the trauma and/or dissociative reliving of the trauma)
•Avoidance to the point of having a phobia of places, people, and experiences that remind the sufferer of the trauma or a general numbing of emotional responsiveness
•Chronic physical signs of hyperarousal, including sleep problems, trouble concentrating, irritability, anger, poor concentration, blackouts or difficulty remembering things, increased tendency and reaction to being startled, and hypervigilance (excessive watchfulness) to threat
The emotional numbing of PTSD may present as a lack of interest in activities that used to be enjoyed (anhedonia), emotional deadness, distancing oneself from people, and/or a sense of a foreshortened future (for example, not being able to think about the future or make future plans, not believing one will live much longer). At least one re-experiencing symptom, three avoidance/numbing symptoms, and two hyperarousal symptoms must be present for at least one month and must cause significant distress or functional impairment in order for the diagnosis of PTSD to be assigned. PTSD is considered of chronic duration if it persists for three months or more.
