@Castle -
The 'act' is something some NPD and HPD types engage in, so we try to become some ideal that others want. The big problem being eventually it bubbles the surface, you don't really like me, you like the act, the show. Gets back to what we struggle with. What was so wrong with me that a parent/guardian couldn't just love me, why the constant disapproval, and criticism?
I write 'some' because there is a world of difference between those motivated out of core self-esteem damage, and those who learned they are entitled. They can look the same. The entitlement minded are just not prepared to deal with threats to their over-the-top view of self, but those motivated by broken self-esteem, it's a struggle to feel good for even a few moments.
