List characteristics expect after someone was diagnosed with narcissistic or hysterical personality disorder?

You mean "histrionic personality disorder"? When cornered about their actions, many individuals with histrionic personality disorder tend to lash out. An ER doc isn't the best person to be making that diagnosis though, so you need to get a second opinion from a mental health professional. Tell this person that they can get plenty of attention from someone who is willing to listen if they go see a counselor.
