I think you need to start by saying that you are there for him.
What is your relationship with him?
Does he live in Europe or is his "home" somewhere else.
Does he have any family anywhere.
He sounds desperate, and very very sick.
It also sounds like he is self medication with alcohol. This would indicate some kind of chemical imbalance.
I think that the starting place would be simply to state that you are there for him. Then you can move on to urging him to get help for himself. He will need to trust you first before he will listen to you.
He's like a close family to me. We tell each other everything. I'm going to talk him in seeing a psychologist. I really hope he would go.
