Does anyone know the name of this song?

Question

I've been through all the search engines and nowhere can tell me who sang this song or what the name is. Starts off with:
"Doesn't matter what you say
Why's it gotta be this way
I've seen the things you do
When I am not with you"

And the next part I know I've heard right is:
"And the world is falling down down down
And you're nowhere to be found
I don't wanna mess with you
Maybe that's what I should do
I'd do
Anything
For you
Stupid me"

Does anyone know what song this is?
