I am Set in Stone (A Shakespearean Sonnet)

I will not change myself for you, not for
Anyone, not even if you "love me."
If you don't like this, well there is the door,
For this is me and I will roam most free.

The scars of love and evil deeds have cast
Upon these eyes a shadow cold and dark;
But all the tears that trace my cheeks are past
After I hear the song of cheery lark.

And happiness is key to smiles and I,
I have the key but, oh, how fake it is.
No, I won't be "blue or violet sky;"
These feelings bubble up in me like fizz.

You may think that I am crazy or deranged,
But this is me and I will never change.
