They won't call the suicide hotline for you. They won't transfer you. They won't share their number. What they'll do is send the police.

I can safely say, in retrospect, that although I survived it, it took nearly a decade to fully heal from that event. But in the mean time, I also learned (thanks to posts like these) about the Samaritans and later in the UK, they helped me get through the tougher moments of this process.

I don't know how significant the effect is, but it's non-zero. :)
