I can honestly say I don't recall ever thinking of it, until I tried to do it ('no option'). Post that someone brought up they had tried and I ran for the hills. Maybe about 7-10 years later I dealt with SI on and off, assumed it was depression, yet recognized I could both get 'depressed' without understanding why (a lot to do with denial and flashbacks, physical or emotional), and yet conversely how could it be physiological if 'words' could turn around my thinking? (Much like Dr. David Burns says about thoughts and beliefs). About 15 years ago it came up again after sort of dissociating-from a bad experience, and during a bad time in my life. It hung on like a dog with a bone after that.
I really like what

I asked her if after what I’d told them she was surprised I’d say I felt like that, and we both sorta laughed.
I think this is true, and I think not all SI is of the same flavor. I don't know much about C-PTSD, but I do agree with the possibility of emotional flashbacks. I think the thing about SI is, like any other symptom, it can be more complex than it appears. I had a relative once, diagnosed with a particular condition. She seemed to have passive-aggressive behaviours. And yet, in so many ways these seemed contrary to her 'heart'. (?) The truth was, I was assuming an ~'intent' of sorts, when it really had to do with working memory, and excutive function. I was ignorant of what her condition involved. When I realized my error(s), it made sense. And tbh that was my fault, not hers.
For me, I think SI is as
@Mach123 said, no more and no less. Thrown in with an (un)healthy heaping of powerlessness, and exhaustion. And seeing it as an option, because really it's just comparing subjective pain levels within the options.
But like
@Eagle3 said, to talk or laugh about it, and not make things worse is helpful. It grows in the dark, I think. (Though I would never befriend it, because it's no friend of anyone, to me. The only truth in it is it isn't bad to not want to be a burden, or not want to hurt other people. )
