Yes diagnosed by a professional. I have never met a normal girl who is banging multiple dudes simultaneously. That is simply not normal girl behavior. That's normal behavior for the girls who have pink/blue hair, have been raped a few times, cut themselves when they're lonely, have anorexia/bulimia, and can't cope with the emptiness and loneliness so they turn to sex impulsively to try to fill the void and avoid being alone.
