The events of yesterday, today, and .... tomorrow?

Yesterday I was in love with you.

Today I'm dying for you.

Tomorrow, I'd have died for you

But again, I'm faced with the question. Who are you?

Yesterday I believed you...

Today I see your lies weren't true, not a single drop of truth.

Tomorrow, we are through.

But again, I'm faced with the question. Why does it matter?

Yesterday I was a child.

Today I am a woman.

Tomorrow I am gone.
