Any counselor or even a good friend would consider the person's situation.
Questions like
"What 's going in in your life right now?"
Most JWs don't consider that's it's their religion (and if their spouse and family are in the same religion) then every emotionally influential person in their life that is inducing in them feelings of chronic invalidation and self-doubt.
The sort of long term toxic self-doubt that erodes away a person's ability to trust their own judgement, perceptions and feelings.
WT as a religion and belief system is the cause of many JW's depression - cause and effect.
Especially the women who are bullied into believing they are crazy, or depressed if they feel anything other than joy at being deemed by the men in their lives as being useless (except for wifely or motherly duties) and voiceless, powerless and inacapable to make even the simplest decisions for themselves without the approval of the group.
Of course JWs are depressed and suicidal, to be otherwise would mean you have a adjusted to very unhealthy situation. The depression is sign there is part of you that knows something is very, very wrong in your life as a JW that you need to fix.
