That's an extremely broad question. I will copy / paste the poem below, and start my analysis of questions you need to bring up and answer in your essay. Four pages is tiny for a Poe poem, you should have no trouble expanding:
It was many and many a year ago,
In a kingdom by the sea,
That a maiden there lived whom you may know
By the name of ANNABEL LEE;
And this maiden she lived with no other thought
Than to love and be loved by me.
I was a child and she was a child,
In this kingdom by the sea;
But we loved with a love that was more than love-
I and my Annabel Lee;
With a love that the winged seraphs of heaven
Coveted her and me.
And this was the reason that, long ago,
In this kingdom by the sea,
A wind blew out of a cloud, chilling
My beautiful Annabel Lee;
So that her highborn kinsman came
And bore her away from me,
To shut her up in a sepulchre
In this kingdom by the sea.
The angels, not half so happy in heaven,
Went envying her and me-
Yes!- that was the reason (as all men know,
In this kingdom by the sea)
That the wind came out of the cloud by night,
Chilling and killing my Annabel Lee.
But our love it was stronger by far than the love
Of those who were older than we-
Of many far wiser than we-
And neither the angels in heaven above,
Nor the demons down under the sea,
Can ever dissever my soul from the soul
Of the beautiful Annabel Lee.
For the moon never beams without bringing me dreams
Of the beautiful Annabel Lee;
And the stars never rise but I feel the bright eyes
Of the beautiful Annabel Lee;
And so, all the night-tide, I lie down by the side
Of my darling- my darling- my life and my bride,
In the sepulchre there by the sea,
In her tomb by the sounding sea.
The poem is about a narcissistic obsession, not a person, if you just glance at it. But when you really dig down, Annabel Lee isn't just a person, it's a representation of an idea. It's the loss of a freedom, of a life. It's about a person who sees this girl locked away, and he can never reach her. This girl put to death and buried in the sea, and he can never have her. It's a burning desire for an emotional or physical freedom that he can never have.
It is:
A slave looking for freedom.
A love that can never be.
A toy that can never be had.
A dream destroyed.
It is the feeling of wanting, but never having. If you read this as a romantic interest, read it again. This applies to everything in our lives that we want and cannot have. Annabel Lee is a metaphor for our desires, and the poem is about the feeling of never having that which we desire, so we pretend.
