All I Need lyrics

Looking back I can see why you would leave.
I never knew what life would be like without you here.
But it's all been said before, and it's all been done before.

I know you'll never be the same.
I know it's got to be this way.
I know you're all I need tonight.
[ Lyrics from: http://www.lyricsmode.com/lyrics/f/forever_changed/all_i_need.html ]
A second chance is ever on it's way.
When you return I will do anything to make you stay.
But it's all been said before,and it's all been done before.

I know you'll never be the same.
I know it's got to be this way.
I know you're all I need tonight.
I know you're all I need tonight.

And you say you don't want to think about how I'm here for you when you're down and out.
