Brief Answer:
It is borderline personality disorder likely

Detailed Answer:
Hello,

Thanks for writing to us.

I can understand your concern and care for your granddaughter.

I think doctor was telling about borderline personality disorder. In this disorder people behave impulsively with energy and take risks like they have taken adrenaline that is why sometime it is called adrenaline personality disorder.You wrote,"easily stressed, emotional, very angry and is beginning to hurt herself."This suggests possibility of borderline personality disorder also.

Common symptoms are:

Intense emotions and mood swings.
Harmful, impulsive behaviors. These may include things like substance abuse, binge eating, out-of-control spending, risky sexual behavior, and reckless driving.
Relationship problems. You may see others as either "good" or "bad" and may shift from one view to the other suddenly, for minor reasons. This can make relationships very difficult.
Low self-worth.
A frantic fear of being left alone (abandoned). This fear may lead to frantic attempts to hold on to those around you. Or it may cause you to reject others before they can reject you.
Aggressive behavior.

Other symptoms may include:

Feeling empty inside.
Problems with anger, such as violent temper tantrums.
Hurting yourself, such as cutting or burning yourself.
Suicide attempts and suicidal thoughts.
Times when you feel paranoid or lose a sense of reality (psychosis).

Treatment approach:

As early as treatment starts better the results.
Both psychotherapy and pharmacotherapy are needed.

Pharmacotherapy: Depending upon symptoms anti depressant (like SSRI), Mood stabilizer(like valproate), sedative-anti anxiety (like benzodiazepine) and anti psychotic medicines are required.

Psychotherapy:
Cognitive behavioral therapy (CBT): CBT can help people with borderline personality disorder identify and change core beliefs and/or behaviors that underlie inaccurate perceptions of themselves and others and problems interacting with others. CBT may help reduce a range of mood and anxiety symptoms and reduce the number of suicidal or self-harming behaviors.

Dialectical behavior therapy (DBT): This type of therapy focuses on the concept of mindfulness, or being aware of and attentive to the current situation. DBT teaches skills to control intense emotions, reduces self-destructive behaviors, and improves relationships. This therapy differs from CBT in that it seeks a balance between changing and accepting beliefs and behaviors.
Other psychotherapies are there but CBT and DBT have proven very effective.
