The only song I think I can really identify with now is "At Least I'm Not As Sad As I Used To Be" by fun. And only the second verse describes me.

And they said, HEY NATE!
"Yeah it's been a while"
"Are you gonna sing?"
Ha! I began to smile, I said
"Oh you should have seen me
A couple of years ago
I was laughing and drinking and smoking and singing" Oh

"Come on can you count all the loves that didn't last?"
It's such a gasp when you bring up the past

So I left, that is it, that's my life,
Nothing is sacred,
I don't keep friends, I keep acquainted
I'm not a prophet, but I'm here to profit
That's all, I'm gone! That's my life, nothing is sacred
I don't fall in love, I just fake it.
I don't fall in love, I don't fall in love.
