@naazira,
I few times elders would knock on my door or call me. But, nothing big. All my family are JWs so i think they would send an elder to check in on me every so often. Might not be the case with your buddy.
Now, it's a little different. I am married to baptized sister, so elders have been coming around more often to "visit".
Elders don't really care for the most part. Yeah, a few do, so don’t get me wrong. Some are great people that only want the best for their "flock".
The majority of ones i have known have usually been indifferent about personal feelings or issues. Unless they think you are screwing around or smoking dope, they probably don’t care. They have their own issues.
Your friend should get professional help. Going back to meetings and counting on the BOE to provide any encouragement will only increase his depression.
Thats my opinion. Hope he gets the help he needs.
