How to cheer a friend up?

[Alpharhodes]

How do I make him cheer up a bit, he's just going off his head, my friend is 20 today and posted this status:

'Although it is my birthday, I don't care, I don't celebrate it. Wouldn't make a difference to me if I was young or old. I would appreciate it if you do not wish me a "Happy" Birthday. Especially when it takes Facebook to remind you when it is. There ain't nothing happy about getting older. I don't need your pity'

A girl broke up with him like 3 years ago, and ever since he's just been moody, and just doesn't care about life any more, it's still a shame though because nobody is wishing him Happy birthday despite him saying not to, he won't talk to nobody, what can I do?

He's also been sending a lot of explict pictures of him self to random girls, and has started drinking/smoking when never in his life has he ever touched a cigarette or alcholol, I know he's depressed but why is he doing this to himself?

Go and wish him a happy 19th birthday, for the second time. He might not feel as old.
