Hello, I'm new to the forum but have been reading a lot of your posts, it's been very interesting.
I remember about a couple of years ago someone from my mothers congregation said that an elders wife was on medication for depression. They went on to say this is the case of many in the truth lately, very depressed and using medication. I don't know about alcoholic, but my mother has been largely inactive for 20 years, so we don't know very much about what goes on internally.
Funny thing is, they attributed the cause of their anxiety and depression on "this system of things" getting worse, it was a sign of the end so to speak. It seems to never occur to them that it might be the jw mindset and lifestyle to blame, but they are in the thick of it. Also, I think that something can be said for trying to numb oneself to some of the things that go on. I went to a bookstudy awhile back to see how things were, from a new perspective, after knowing what I do now. It shocked me when the lesson reader said," as we know we cannot solve any of our problems, only Jehovah can do that". I thought that his comment, and the fact everyone was in agreement, spoke volumes. Maybe they see their mental problems as something Jehovah will take of, just like all the rest of their problems.
