I need help writing a narrative poem. My poem needs to include: -2 examples of imagery -2 examples of alliteration -2 similes -1 metaphor ...

First of all,
remember that a narrative poem is one that tells a story. And, while there may be elements of
narrative in the poem you have posted, it seems to be rather more a confessional than a
narrative poem. So, it is in your best interests to take a different approach to your
poem. 

One approach that you could employ is to compose a setting in which
there is the usual development of a story with a distinct beginning to the action, a middle, and
an end.  Certainly, you can still use this section of your poem:

I leave to save my guardian

The[explain in the first part what this
irony is] is killing me

As is the oncoming danger ahead.

I
am about to fall

Its [what is it
