Heard this morning that a dear friend's chemo hasn't worked and that he won't be with us very much longer. He's long suffered with depression and the dark cloud has fairly obviously descended with his cancer. We'd been keeping in touch via e-mails and texts but a couple of weeks ago he rang when he knew I'd be out and left a message saying that we weren't to try to contact him again. Now he won't even see his DS. Is there anything - apart from pray - that I could or should do?
