I think that this issue depends on how we are all interpreting the word "depression" Just saying oh I lost my job, I am depressed doesnt mean that you are clinically depressed. It almost would have been better if the medical profession used a different term than just "depression" to mean clinical, chemical based depression. How many of us say that we are depressed sometimes, but we all dont pop pills for it.
Anyway getting back to the thread comments I believe the WT is actually referring to the non-clinical depression in this article. Even the CO's admit now in our elders meetings that some may need medication to control the various "depressions" that plaugue many today. America seems to be rife with clincally depressed people, not just JWs either.
