I hope that theres a way we could help him fight his depression .
That would be my hope too.
While there is nothing wrong with calling him, having to make phone conversation might be difficult for him if he is severely depressed--it might be an additional source of stress for him, particularly if a number of people suddenly start calling him. The OP indicates that communication with him is difficult.
It would be good if we could continue to express our feelings and concern for him in threads like this one, and in PMs and e-mails, and there was a way of making sure he could see and read them, and re-read them, at his own pace, and as often as necessary. If he can sign into his A2K account, perhaps a social worker, or even a nurse, at the facility he is in, could print these out for him--helping to relieve his depression in that way should be a part of his treatment.
I have been worried about Andy because his recent absence has been quite noticeable and he has been missed. As others have mentioned, he is always such a gentleman, something that has, unfortunately, become a rarer and rarer commodity at A2K recently. And his always thoughtful, intelligent, articulate comments have made him a valued contributor and one of my favorite people to read and interact with.
I am so sorry to hear he is going through such a difficult time. I hope there will be something we can do to lift his mood at least a little. Knowing how many of us care about him might help.
