One might take note of the differencebetween self harming and suicide attempts.
When one cuts, if the cuts are across the arm (right to left) they are cutting. If the cut is from wrist to elbow, that is a suicide attempt.
It is an attempt to control something. Usually a time of stress. Others here have described the addictive quality of cutting due to the chemicals released in the body.
I also think that people that insist on surgeries, and broken bones, accident prone, etc are also self harming.
Tattoos, piercings etc are the socially acceptable way of self harm.
This style of harm is from the Africans. Tribes would decorate and pierce their bodies as rituals.
This really scares me- my ud19, a recently self proclaimed cutter with an eating disorder, came home with 2 cuts from her wrist to her elbow. She had been drinking liquor with her 26yr old bf, his friends puring while they celebrated his birthday. They woke up hungover, and had to go and get her stitches. My daughter joined the military a little over a year ago, with great encouragement from her uASPD/NPD/BPD father. She hates it. Her bf is also in the military- seems like a nice guy- immature, but nice. He obviously cares for her, and was freaked out by her actions.
I'm not sure how to support her in her healing. I expressed my concern, especially about infection. She lives 6 time zones away from me. I send her a card/letter every week, frequent texts throughout the week, a monthly care package. I wrote to her chief from A-School expressing my concern for her (yes, I contacted the military to try to get my kid help). She is now on a bunch of meds that I think are doing more harm than good. And she is spending very little time on her leave with me. She is spending the vast majority of her time at her father's, where crazy is normalized. He is PD'd and the stepmom is eating disordered. I will hopefully be able to drive her to the airport tomorrow, so I get that 2 hours with her and the bf, but her dad may step in. Out of the 6 days she has been on leave, I have only seen her a handful of hours.
