I believe this, and it mirrors what I have heard from suicide attempt survivors in my personal life too.

I do wonder what the story would be if we could somehow ask the people who didn't survive. Likely a purely philosophical question with no answer, but I wonder how many of the people who do end their own lives don't regret it at all.

Most likely the dead are not capable of regret, but if there is some manner of afterlife where people can contemplate their actions, I do wonder how many of them would regret their suicides
