Mental Health Support

It would help if you are not the only one, both for yourself and him. If you can contact someone who can get in contact with him personally that would be good. You shouldn't have to deal with this by yourself. If you don't know his address then there really is very little you can do. If you can't do any of the above I'd directly ask him if he is suicidal. If he says yes or makes it sound like yes then I would contact the emergency mental services in his area and give them his phone number. Even without an address maybe they can do something. If you can't get a hold of anyone that knows him and he says that he isn't suicidal then there's not much you can do. You've already done the best thing by letting him know you are worried. Keep checking in on him regularly and try not to let this effect you too much Remember that even in the WORST possible outcome you can't blame yourself for anything!! If he is truly a friend he wouldn't want that anyway.

Again sorry for the gloominess. Depression is gloomy all round.
