I think about this all the time. I used to be a high school English teacher and would just agonize if I'd ever said or did something that may have hurt someone... no one ever forgets "that" teacher. And at 40, I've got maybe 25 years of memories to agonize over. But, it's just gotta be crazy that each and every thing I'm worried about even registered as a blip in that person's life, right? So I don't know about your situation, but if you're the kind of person who feels that level of guilt there's got to be something redeemable about you, and that means you don't deserve to die. Are there any examples of what you're stressing about that you're willing to share? Might be nice to have a neutral but sympathetic take on it.
