The silence is disturbing

My best friend lost his job on August 1. When it first happened, he called and emailed me a couple times a day. But for the last month, he's been very quiet.

If I want to talk about my mom, he's completely there for me. But when it comes to him, his family and his job situation, all I hear is crickets.

I fear he's getting depressed. He mentioned once (once!) that he feels "isolated," that people mean well and offer to help but then never call back. Since I want him to know he's not alone, I still email him every day.

More than once on this blog I've referred to him as Eeyore because of his tendency toward melancholy. So I'm worried.
