Is This The End Lyrics

Is this the end?
Why does it feel
like we'd only just begun?
I thought we were done.

[ Lyrics from: http://www.lyricenter.com/e48800-zee_avi~is_this_the_end_lyrics.html ]
I think I'll hang on
if you still want me,
but if you don't
I guess I'll move on.

But if you need me,
close your eyes and dream.
I'll give you back your key.
Will you be happy?

Said we'll leave it alone,
but I'll be here long.
And when I'm gone
I guess then we'll know.

I think I'll hang on
if you still want me,
but if you don't
I guess I'll move on.

I guess I'll move on,
I guess I'll move on.
