It is common for dissociative people who believe they have multiple personalities, to struggle with affect regulation – meaning that their emotions are all over the score board and coping with them is not their strong point.
In a warped manner of coping, there is non-suicidal; the most common is cutting their bodies. Some people cut in places that can be easily hidden by clothing like torsos, thighs, and groin. Others make repeated injuries to their forearms, wrists, or legs which are not as easily hidden – I question the chosen location of the cutting wondering if it is done to elicit reactions from other people who can observe their bodies. I lean towards the attention getting aspect because that was what I witnessed while an in-patient at a psychiatric hospital receiving treatment for multiple personalities.
What I saw with patients who self-harmed is that wearing white bandages was a badge of honor. It meant that they did something in secret that instantly became very public. Even so, their secret remained hidden behind bandages and left the rest of us patients to wonder why they hurt themselves. Cutting let everyone know they were in pain and desperate, but it did even more.
In my opinion, it demonstrated that they had courage. The kind of courage I wish I had had, but didn’t. I wanted to get better (from mpd, an illness that never existed) and decided that when I was well, I did not want scars running rampant across my body like a road map.
I was somewhat envious of them. Their determination and seeming lack of fear was admirable – at the time. Here we were all 21 of us locked in a hospital unit together and only one or two of us took self-harm to the wall and injured seriously enough to leave the unit on a stretcher. Pretty ballsey to be in the intensive care unit of a psychiatric hospital – locked in 24 hours a day – and still find an escape, even if it meant lots of blood and an ambulance ride to another hospital.
I don’t find self-injury an admirable quality anymore. It’s quite a sad situation as I see it. Those who do it claim that it brings release. OK. I’ll accept that as their experience. The result remains. There is always an element of attention seeking involved.
Taking cutting to higher level, some keep the wounds from healing by picking at it or re-injuring the area. Yes, this does happen and an mpd/did friend of yours could be engaging in this behavior. Although I suspect you know about it because telling or hinting about it is titillating for injurer and their audience.
