We know that a personality disorder is a way of relating to the world at large that constantly leaves us and the people around us feeling uncomfortable, shortchanged or downright unsafe.
Borderline personality disorder is what results from a way of interacting with our primary caregivers when we are not confident that they truly love us. As a result, people with BPD go through life trying to get other people to give them the unconditional love or parenting that they did not receive as children.
As per Dr. Elinor Greenberg, the primary preoccupation of a person with a borderline personality is therefore love and care. This means that you probably have BPD if the motivation behind the things you find yourself doing is to get someone to care for you, regardless of your age and social stature.
