I barely knew the guy, and there's a large part of me that knows I did basically everything I could possibly do to help. I wasn't a family member, I wasn't his spouse, I wasn't a childhood friend, I was a dude who had an SA account as a teenager and subscribed to his YouTube channel and found his LinkedIn.
....That said, and I will acknowledge that this isn't the most rational thought that I have ever had, but I do wonder if him saying that to me was a cry for help, like he was reaching out to anyone to show some sort of interest in his well-being.
It's silly, and of course that logic will never end; I'm sure could convince myself that I'm responsible for 9/11 if I tried hard enough.
As I said in a sister thread, I do have an appointment with a shrink in a few days. I am reasonably sure they will either be able to help me or at least will be able to refer me to someone who can.
