Some words disappear with time, but certain things a parent says can stay with a child well into adulthood. For adult children of narcissistic parents, those memories may resurface during arguments, major life decisions, or moments when they question their own worth. Narcissistic parents may use criticism, guilt, comparison, or denial in ways that teach children to doubt their feelings and constantly seek approval. Importantly, hearing these phrases does not automatically mean a parent has narcissistic personality disorder, which requires professional assessment. Still, recognizing unhealthy patterns can help adult children understand why certain words continue to hurt.
