Hi,

I think you're doing pretty much everything you can do for your friend. You've reached out, been there for him, tried to let someone else help, as well, so, I think just continue to stay in touch with him. Just continue to the kind of friend you are to him. At the end of the day, he has to make the final choices for his personal welfare and you can only carry him so far.

As I say, just continue to be a supportive friend, it's all anyone can ask for.
