"I'm really upset right now. I just found out one of my students is a cutter. I need to find an appropriate way to get her help. Details after a nap."
She may have Borderline Personality Disorder.
The only real hope for them is Dialectical Behavioural Therapy.
What you need to know is they are pathological liars, self injurers (they do this to feel alive), they have an intense fear of abandonment, put on a sweet and nice facade in public but behind closed doors rage at whoever is close to them like you wouldn't believe, often will engage in drug abuse and sexually promiscuous behaviours, tend to have frequent shallow destructive relationships, are physically violent to their partners and threaten suicide if the partner wants to leave them, etc.
Most therapists are afraid to deal with them they can be so toxic to the mental health of those around them and if a therapist does agree to treat them that therapist usually gets themselves therapy to keep their mind straight from having to help such a client but being manipulated all the while as BPD's make you begin to feel crazy the longer you are around them because they do not think like normal people and irrationality seems rational to them.
They draw normal people in by putting on a mask of being overly nice or sweet or shy or quiet. Basically anything that makes them appear non threatening but then the fangs come out for those who get close to them.
Anyway I bring this up to you Cannon to make you aware that this student could be a BPD and since you mentioned self injury since it is one of the huge symptoms of BPD.
The student could just be a self injurer for other reasons but its still good to know about BPD just incase.
