Person, Not Possession
When Maria was born, her father and mother looked to her for the fulfillment of their damaged dreams. They pushed her to activities they felt incapable of doing.
Growing up, Maria felt that her parents owned her by the way they spoke to and treated her. When she refused what they wanted her to do, they'd call her demeaning names.
Under such circumstances, Maria developed a shame-prone "core identity." She felt bad because of disastrous consequences of asserting her individuality, own thoughts and feelings.
Toxic parents are shaming. They treat children as possessions. Not persons, but extensions of themselves.
When children develop their separate and unique identity, they're seen as a threat by their shaming parents to their personal needs.
The result is, children are not moulded to feel valued as a person. In the shaming process of being treated as a possession rather than a person, wrong behavior and self are the same.
This is the reason why unhealed people who are shame-based end up spreading the shaming process in relationship with others.
Without therapy or intervention, the cycle perpetuates itself all the time. Affirming the mental template of badness - a possession rather than a person.
