That Was Yesterday by Foreigner

I thought I knew you well, but all this time I could never tell
I let you get away, haunts me every night and every day

You were the only one, the only friend I counted on
How could I watch you walk away, I'd give anything to have you here today

But now I stand alone with my pride, and dream that you're still by my side

But that was yesterday, I had the world in my hands
But it's not the end of my world, just a slight change of plans
That was yesterday, but today life goes on
No more hiding in yesterday, 'cause yesterday's gone

Love, my love I gave it all, thought I saw the light, when I heard you call
Life that we both could share has deserted me, left me in despair

But now I stand alone with my pride
Fighting back the tears I never let myself cry

But that was yesterday, love was torn from my hands
But it's not the end of my world, just a little hard to understand
That was yesterday, but today life goes on
You won't find me in yesterday's world, now yesterday's gone

Goodbye yesterday, now it's over and done
Still I hope somewhere deep in your heart, yesterday will live on
