I’m a shrink. Over the past 25 years I’ve probably seen several hundred new patients every year who wanted nothing more than to kill themselves.
Only five ever did that I know of, and not one of them did it over something like a scandal that I know of.
In fact, I don’t recall even a single one out of the many hundreds whose suicidal thoughts were motivated by a scandal or getting caught in an affair or something illegal or embarrassing.
Happens in movies all the time, but in real life it seems limited to “politics”.
It seems to happen lot in young men who’ve been picked up drunk, at least in my neck of the woods.
