Ordinarily, the child’s developing internal world and sense of himself should be protected, encouraged and nurtured by his primary caretakers.
When this does not happen, or when the primary caretakers are infact provocative, attacking and aggressive towards the child, then unsurprisingly weaknesses may emerge in the child’s psychology.
As the child matures, so these weaknesses may mature too. As an adult the individual is then left with work to do to repair, manage and look after themselves and their psychology effectively.
