This is good!

I like the metaphor of the box, and the enjambement too. Makes it flow well :) One tiny criticism I have is that it feels like it isn't completed finished...or was that on purpose?
Anyway, good job!

Hello.
Your poem --to me-- seems like it is your transition from high school to college (or to moving to adulthood in your life).
On your profile, you said that you're 17, so that should be a pretty good assumption.

I love the rep you use in the poem.
It really gives the reader the feeling as if they are inside a box. Also, the same use of the sentence structure is wonder.

Most importanly, I like the final stanza. It is not like the rest of the poem, which does make the read feel like they are making the change with you. A very nice touch :)

BTW: I am looking for a beta-reader, but I could not find a way to contact you beside a story review (I did like the poem ^^ though) but I am in the need of help. I am working on a poetic novel and novella sort of thing. Would you be intrested in reading either of the two?

Hoping to provide you something good to read,
A.H. Fenald
