I started having strong suicidal impulses while I was a JW. I felt like I was a complete failure, due to being "reproved", having my "priveleges" taken away, feeling like I was never going to live up to Jehovah's Righteous Standards(TM).
I didn't do it because I didn't want to Bring Reproach On Jehovah's Organization (TM).
The urge is still at a low simmer, it would absolutely shatter my family if I were to do it so that keeps me from seriously contemplating it. But if the world were to go absolutely nutso like what I expect, then I don't rule it out as being a perfectly rational option.
