The Emotional Conflict in the Adopted Child.
The child's private conflicts are not shared with the adoptive parents.
The child has learned in early childhood to keep silent of the things that cause confusion, inner turmoil, anger and sadness, due to previous experience of the overreacting adoptive mother's inability to deal with her own problems, and the adoptive parent's denial that a child has problems. The mentality of the adopted mother expresses invalidity at the child experiencing emotional discomfort. The parent's denial expresses that the child "lives a life of leisure" free from the stress of the adult world", a child is incapable of being stressed or to even to know about what the word stress means. Narcissistic personality traits are common behavior observed in adoptive parent's denial of a child's emotional well-being, or denial of the adoptive parent's contribution to to the mal-adjustment of the adopted child.
Emotional Conflict: a feeling of physical discomfort, especially when 'a functional disturbance has become associated with an emotional conflict in childhood', and in particular by tension headaches expressing a state of inner tension...[or] caused by an unconscious conflict'.
Equally, 'Freud's concept of emotional conflict as amplified by Anna Freud, Erikson and others, is central in contemporary theories of mental disorder in children, particularly with respect to the development of Psychoneurosis.
In childhood development
Displacement too can help resolve such conflicts: 'If an individual no longer feels threatened by his father but by a horse, he can avoid hating his father; here the distortion way a way out of the conflict of ambivalence. The father, who had been hated and loved by the child simultaneously, is loved only, and the hatred is displaced onto the bad horse'. But the child's hatred is more about his fear of the father, so the child lives in fear of the horse, instead of hatred of the horse.
...rooted in unconscious instinctual conflicts'. "Instinctual Conflict"
However physical discomfort or pain without apparent cause may be the way our body is telling us of an underlying emotional turmoil and anxiety triggered by some recent event. Thus for example a woman 'may be busy in her office, apparently in good health and spirits. A moment later she develops a blinding headache and shows other signs of distress. Without consciously noticing it, she has heard the foghorn of a distant ship, and this has unconsciously reminded her of an unhappy parting', a physical beating, a local sound from her childhood abusive home.
