I have the same worry when I describe my past to others. I buried my first dog when I was less than 10. My father and I later raised over 10 more stray dogs. We really like dogs hahaha.
But I watched my father being emotionally abused by my stepmom, who was almost 30 years younger than him. My father looked 10 years older in just two years, and then he died in an accident when I was 17. Strangely, I wasn't really affected much mentally by such experiences either. But I can't really say the same if I had any near-death experiences like you though.
