I imagine we all know exJW’s or JW’s who killed themselves or tried to. This forum itself has suffered the loss of good people to suicide and JW pain. It’s a very real issue.
I don’t understand your purpose. If you are asking to find out if anecdotally exjw’s commit suicide, you already know the answer. If you are hoping to get some statistics then that will prove near impossible and for sure you won’t get them from asking for numbers on a forum post. If you are asking for personal accounts of suicide then expect people to not want to offer that up to a stranger online.
Exactly what are you hoping to achieve ? Are you after statistics, anecdotal stories or personal accounts?
