There is only one thing I would like to say that might help, when you said, "I am stronger than you could ever imagine me to be..." It seemed a little stretched, why not try saying...
"I am stronger than you could ever be..." It still makes sense, but you don''t loose the smooth melody that you have going on in this poem. Overall...10.
Sincerely
