What's that song in the movie 'Girl Interrupted'?

Question

Who sings it, and what's the title? It's the song that's playing when "Daisy" kills herself. I know some lyrics are....
"Why do the birds go on singing? Why does the sea rush to shore? Don't they know, it's the end of the world? Because you don't love me anymore"
(Or something like that)
-Thanks.
