I loved this poem, however in your description you said your english wasn't very good so if you don't mind can I suggest some corrections?
"closing us the door" is a little confusing, possibly: "They close on us, the door" to make it still rhyme?
every my step is fall could be 'every step I fall' and also 'leave me there to die' instead of 'let me there to die' and 'sick of that fight' instead of 'sicked'... I don't mean to offend I just think those corrections would make it heaps better, though it's already really good :)
