I know of one instance a few years ago.
Brother in his late 30's, married, 1 stepdaughter, 1 son, 1 (very new) baby daughter.
Had MANY cleaning jobs to make ends meet (I used to baby sit while both parents were out cleaning in the evenings).
With all the pressures from the org, he couldn't take it anymore. He had spoken to many elders in the cong, there was no comfort from the org.
Around memorial time, he drove his car a short distance, and ran a hose from the exhaust pipe into his car, closed the windows and turned on the engine..................................
His wife has since remarried but hates memorial time because of all the memories. She has since asked elders (one in particular) many deep questions about the organisation, which he can't answer, he can't help her. She is still struggling.

Part of my job is to collate suicide statistics for the region. I shall have a closer look and see what I find.
I hate the thought of someone thinking life is not worth living, when all they have to look forward to is many more years as a pressured JW.
