Goes something like this..
When I found I was pregnant, I was elated,
When you were born, I would have died for you
When your heart broke, mine was shattered. ETC
"Before you were conceived I wanted you;
before you were born I loved you;
before you were here an hour I would have died for you.
This is the miracle of life." -Maureen Hawkins
Doesn't match your quote exactly but its all I could get hth.
