My best friends girlfriend ran away from home and he is now depressed, how can i cheer him up?
If he knows where she may have ran away to or has any idea where she is now or later ask him to call the police. She is vulnerable to strangers with bad intentions. And he should talk to his own family for support. I'm glad he has you for a friend.
Just being there with him is good enough! if you really want to help him just hang out to forget about gf!
tell him!! that dont bring that one person hold u back there more ppl in the world that will not bring ur frown upside down.
Nothing is the end of the world. Cheer him up. Good luck.
