"Am I to be made of stone?" - Elizabeth I tribute & character study

A character study. Movies/miniseries used:

Elizabeth R (1971) with Glenda Jackson
Elizabeth (1998) with Cate Blanchett
The Virgin Queen (2005) with Anne-Marie Duff

The song is from the soundtrack of the 2005 miniseries. The lyrics are based on a poem composed by Elizabeth herself.

My care is like my shadow laid bare beneath the sun.
It follows me at all times and flies when I pursue it.
I freeze and yet am always burned
since from myself again I turn.
I love and yet am forced to hate.
I seem stark mute; inside I prate.
Some gentle love doth ease itself
Into my heart and mind.
For I am soft and made of snow
Love, be more cruel or so be kind.

The original poem is called On Monsieur's Departure. Go look it up if you're interested.
