Hi, A person with borderline personality disorder often act impulsively without thinking about consequences. He/ she usually complains of feeling empty and the mood frequently fluctuates. Such a person often show anger outbursts and have unstable relationships with others. A borderline person have a tendency for showing self-destructive behavior (suicide gestures and attempts). Such behavioral pattern is usually present for along duration of time and manifests in multiple situations and not just in a single setting. It is highly recommended that you fix a consultation with a psychiatrist for confirming the diagnosis. Best wishes.
