Sorry to hear you had a traumatic childhood. I can identify with this, I recall many times when I didn't want to live in some of the situations I found myself in, when much younger. It included adults (not family, thankfully) coming down hard on me for crying about losing my only sibling, my younger sister. she was seven, I was ten. She died very unexpectedly and very suddenly of kidney cancer. I can't help wondering looking back, if the pressures on us by having our only active parent suffering from mental illness had anything to do with my sister finding a way out. I used to try to end myself by holding my breath. I thought if I could do that with enough determination I might die. I even tried doing it underwater. It never worked but I got really good at swimming underwater, nobody could catch me, not even adults :)
Anyhow I had similar values to you as an adult, I was determined my own daughter, and any other kids I might have had, would never go through any of the pain that I or my sister went through as a child, but had the carpet pulled from under me by my daughters mother, my ex wife not sharing my values, putting herself first, my daughter's life was turned upside down by a horrible divorce, outside my control, just like my own was at her age, it worried me a lot, but my daughter now is 22 and seems well balanced anyhow, so I thank god for that.
I had cause a couple of years ago to intervene when a kid in my building was making threats to jump out of a window, in my building near where I was sitting having lunch on my balcony, the kid was screaming "I'm gonna jump, I'm gonna jump!" I think it was for the attention of an adult, but I couldn't see or hear the adult, and we are a long way from the ground, it would be a definite leap to death for the kid, if they'd done it, so I shouted at the kid to start behaving themselves, and get back from the open window, which they did, but I still never heard or saw any adult.
Even now I don't know who his parents or guardians might be, but I generally just mind my own business, living on my own now, I find it's best to just mind our own business, whenever we can.
