I don't think people should be ashamed of SI. It is a coping mechanism.
I rarely SI now, which is truly amazing.
This is how it was for ME, this may NOT necc applly to other people.
Fortunately I had a good t that came to understand that I needed SI to keep me safe until I learned other, better coping mechanisms.
She made me not ashamed.
Before I gave myself permission ot utilize SI as a TOOL, I would do other things to help myself, eg, drinking(NOT good, I am alcoholic), drugs, dangerous driving, walking in dangerous places, putting myself in diif dangerous situations, S ideation and beyond....etc
Anything to RUN, anything to make it stop.
Given the alternatives, SI was a better choice. And I worked hard at alternatives, and now I rarely SI.
So to me SI has no shame in that it was a tool, a tool that kept me home and 'safe'.
Goto admit, the scars suck. Seriously suck, cuz its not like I can announce to the world that I SI, but in my heart, I KNOW, I did what I had to do.
Took time, but I do good now.
So don't be ashamed, and know, even a bad SI person like me can stop.
