Queen elizabeth as a poet - thesis statement incompleted

ok im writing about queen elizabeth as a poet, and im not sure what a good thesis statement would be. so far i have,

Queen Elizabeth, like her father, was a poet, and it was of great value to her. Writing poetry helped her to express what she was enduring while prisoner of Woodstock.

i need help completing this statement; need more meat on the bone!

"Queen Elizabeth, like her father, was a poet, and it was of great value to her. Writing poetry helped her Queen Elizabeth to express what she was enduring while prisoner of Woodstock."

Okay, so add an explanation of what exactly it was she endured and how her poetry reflects this specifically, both in form and content.

Right, and you can put "like her father" and other details into your background or body paragraphs.
