Analysis of A Reflection of My Soul

We were so young,
To new beginnings,
You saw through me,
And, I saw you as my sister,
A reflection of my soul.

Thirty years later after,
One happy marriage,
One divorce,
Two children,
You still saw through me,
My sister,
A reflection of my soul.

A year after you have been gone,
My heart is falling into pieces
My spirit is broken,
My sister,
Has been called up to heaven,
A reflection of my soul.
