I ran into stuff like this on a couple of occasions when I was a cop in the military. There are a couple of different psychological disorders that can manifest themselves into self-hurting actions like this for attention. Many times it's not the act of hurting themselves, but the story around the infliction of the injury that matters to them. I saw this in mostly women with undiagnosed Borderline Personality Disorder. Sociopaths will sometimes do stuff like this to manipulate a situation in their life to what they want too. Regardless, she has a major psychological disorder, Axis I or Axis II, no doubt about that.
