My best friend lives far away from me, had a really rough life, especially these past few months where he got kicked out from his home and dumped by his girlfriend.
He told me yesterday that he can't take it anymore, it's too much.
I've seen him sad before but this is a whole new level and it's making me really worried.
I've written to him, telling him to keep on fighting, that I love him and will be there for him, that it will be fine, given him his local suicide line number and so and so.
But it seems that it's getting worse, and I don't know what to do, I can't fly to him because I don't have a passport or his adress, I have no contact with his family, only his exgirlfriend.
Since he has ADHD and is kinda impulsive sometimes it makes me really worried he will do something.

What would you do in this situation?
