What is the full poem of "I gave birth to you before you gave birth to you and you gave birth to me and I am already old"?

Untitled

You were born before I was born, but I was born before you were old.

You hate that I was born late, and I hate that you were born early.

You were born before I was born, but I was already old after you were born.

I wish I could live with you at the same time, but I will be with you every day.

I was not born before you were born, but you are already old after you were born.

I am far away from you, but you are separated from me by the corner of the ocean.

I was not born before you were born, but you are already old after you were born.

I turn into a butterfly to find flowers, and roost on the grass every night.

The meaning of the whole poem is that when you came into this world, I was not yet alive, but when I came into this world, you were already old. You hate God for letting me be born too late and I hate God for letting you be born too early. I hate God for letting us not be born on the same day, same year, same month, and be with you every day. You and I are separated from each other by the ends of the earth. You and I might as well turn into butterflies and flying flowers, accompanying each other day and night without separation.
