Your personality is your unique way of thinking, understanding, reacting, and relating to people.
A personality disorder isn't just an unusual personality. It's when your personality traits cause significant problems in your life or keep you from relating normally to others.
Borderline personality disorder is:
People with borderline personality disorder often:
Become panicky or angry when a friend is a few minutes late or cancels an appointment, which makes them feel abandoned
Have a quick temper and lash out verbally at friends, partners, and family, particularly when they think someone isn't meeting their high demands for support
Shift their views rapidly, such as going from praising someone to suddenly being overly critical
Impulsively do unwise things, such as having unsafe sex, overspending, driving recklessly, using drugs, or drinking too much
Sabotage themselves when about to reach a goal, such as dropping out of school right before graduation
Hurt themselves on purpose, such as by cutting or burning
Create crises, such as attempting suicide, to keep other people from abandoning them
Although most self-destructive things they do aren't fatal, almost 1 in 10 people with borderline personality die from suicide.
Even though they're needy, people with borderline personality disorder typically have unstable relationships. They may suddenly go from idolizing a friend to criticizing and dumping them.
