The Eldest Daughter
Syndrome.
It is an open secret in psychology: The Eldest Daughter is rarely just a child. She is the "Third Parent." From a young age, she is tasked with emotional labor, conflict management, and setting the example.
This results in a personality profile characterized by High Conscientiousness and Pathological Self-Reliance. As an adult, you may find it impossible to ask for help because your brain equates "needing needs" with "failure."
