Definately NOT like the following which describes my MIL to a tee:-
Responsible Child" - "Family Hero"
This is the child who is "9 going on 40." This child takes over the parent role at a very young age, becoming very responsible and self-sufficient. They give the family self-worth because they look good on the outside. They are the good students, the sports stars, the prom queens. The parents look to this child to prove that they are good parents and good people.
As an adult the Family Hero is rigid, controlling, and extremely judgmental (although perhaps very subtle about it) - of others and secretly of themselves. They achieve "success" on the outside and get lots of positive attention but are cut off from their inner emotional life, from their True Self. They are compulsive and driven as adults because deep inside they feel inadequate and insecure.
The family hero, because of their "success" in conforming to dysfunctional cultural definitions of what constitutes doing life "right", is often the child in the family who as an adult has the hardest time even admitting that there is anything within themselves that needs to be healed.
