Impulsive, self-destructive behaviors. If you have BPD, you may engage in harmful, sensation-seeking behaviors, especially when you’re upset. You may impulsively spend money you can’t afford, binge eat, drive recklessly, shoplift, engage in risky sex, or overdo it with drugs or alcohol. These risky behaviors may help you feel better in the moment, but they hurt you and those around you over the long-term.
