I loved the imagery of emptying and refilling cavities. That said, this has a couple typo. That said, I like that the speaker puts her life into someone else's hands, I think that's a good message to send. Also, I think the first two lines would be more concise if it was "i'm a skeleton/ closet for hope, desires," plus there is still enjambment with the line break. Also, and this probably wasn't intentional, I like that "i'm" is not capitalized because it shows that the speaker is thinking lower of herself than the person being addressed in the second person.

I hope that's a good review. :)
