Can't comment on the case but re mental health issues I remember when I was attending meetings a guy gave a talk and highlighted that some governments (of course he didn't say what governments mind) had deemed JW teachings as being detrimental to mental health and caused depression. He and the audience scoffed quite predictably but at the time I remember thinking it was true!
There were definitely some people who could not handle being a JW psychologically or emotionally, I had witnessed it myself. Emotionally/psychologically fragile people tipped over the edge by the litany of unreachababe congregation expectations, gossip and the general small minded ignorance of disability and or mental health issues by the elders only compounded the problem.
These people all left and at the time I thought good! Leaving, walking away was the most sensible thing they could do!
Get out!
