2, my cousin and a work colleague.
Two of the nicest and genuine guys you coud ever meet. Really decent and very alike, perhaps just coincidentally.
My cousin went into a downward spiral after a traumatic event - ended up turning to drink, marraige broken down, job lost etc - in engaged with services, got sober, had a new job, house etc. Ex wife, family, everyone supportive but he was just tortured and haunted by what happened (none of which was his fault).
Work colleague, I don't know as much and on the surface, no one knew he was struggling at all. He was a fantastic person and such a great loss too.
Fortunately, I know another who reached out after a suicide attempt & was found on time & has done extremely well since after a lot of treatment. I was almost a stranger to this person but they called me when doing it for the most bizarre reason & thankfully emergency services got there on time.
I've posted this before but Ohana do a free, online suicide prevention course. It's less than a half hour to do. I found it useful. https://www.ohana.ie/
