Lyrics:

I know, I shouldn't walk out this way
Sorry, but my feelings have changed
I would only hurt you more if I stayed
So I can't go on pretending that I feel like I did yesterday

So, I can't stay and keep living this lie
I finally found the strength to say goodbye
I'm on my way, nothing can change my mind
I'm leaving behind what we had yesterday

Know this, it's not about somebody else
It's not you, I just need some time by myself
Though it hurts me to see you go through this pain
Still I can't go on believing that I feel like I did yesterday

So, I can't stay and keep living this lie
I finally found the strength to say goodbye
I'm on my way, nothing can change my mind
I'm leaving behind what we had yesterday

Throughout this time I've realized
Been holding this in far too long
But I have to be strong, can't turn back
I've been there for you and now I must do
What I should have Yesterday

I can't stay and keep living this lie
I finally found the strength to say goodbye
I'm on my way, nothing can change my mind
I'm leaving behind what we had yesterday
Yesterday
Yesterday
