'Elephant' by Damien Rice

What's the point of this song? Or even singing?
You've already gone, why am I clinging?
Well I could throw it out, and I could live without
And I could do it all for you
I could be strong
Tell me if you want me to lie
'Cause this has got to die
This has got to stop
This has got to lie down, down
With someone else on top
