I think there are many reasons why the ORG is Prozac Nation. Probably the biggest reason for anxiety and stress is that there is no rest.
I think something as simple as keeping the Sabbath would work wonders.
There is never a day of rest for JWs as I have heard JWs say 'isn't it even better to give ALL days to Jehovah?'
The day of rest was given to refresh your spirit and body from God, not the other way around.
There's not enough Prozac in the world to give rest when you NEED rest.
just my opinion
