My (presumably) man, get better friends. If I can make a friend of mine feel better by listening to him, why wouldn't I? I may not know what to say, but I would try my best. The saddest (on an inter-personal level, not as in "the world is going to shit") thing I experienced recently was a friend of mine basically disappearing because of mental health issues. I think I understand why he did that, comparing yourself to others sucks, but I wish I could help him more than the occasional "hey, how are you doing?" when we randomly meet somewhere.
