this is very good. especially the premise, i have written some things on the same idea as well. to improve it i suggest making it flow better, less nouns, more actions and a little punctuation then to clarify. for example the last stanza could become:

I am trapped and suffocating

in me

yearning for freedom;

trying to fight

a way out of me.

been trying for so long

fought for so long

I'm wishing I could stop

but only I can beat myself

this was a little extreme, you could just try changing a line or two in each stanza or such. i did notice alot of it was stalysitc and to create a tone and feeling ect, which was great, but then at other parts you have to break out of that to prove that it was purposeful and show what a great writer you are, and to lend more emphasis to the stark quality you put inthe beginning to tell a story. a difficult but important distinction.

however, it is a very good peice, on an important and large topic. write some mroe about this, i have found it to be a strong basis for many very different poems.
