Please Help! 100 Points! The Rainy Day
By Henry Wadsworth Longfellow

The day is cold, and dark, and dreary;
It rains, and the wind is never weary,
The vine still clings to the moldering wall,
But at every gust the dead leaves fall,
And the day is dark and dreary.

My life is cold, and dark, and dreary;
It rains, and the wind is never weary;
My thoughts still cling to the moldering past,
But the hopes of youth fall thick in the blast,
And the days are dark and dreary.

Be still, sad heart! and cease repining;
Behind the clouds is the sun still shining;
Thy fate is the common fate of all,
Into each life some rain must fall,
Some days must be dark and dreary.

So my question about this poem is the rhyme scheme. Every stanza ends with the word "dreary." So for the first two stanzas, the rhyme scheme would be AABBA because the last word of the last line rhymes with "A" the last word of the first two lines. But the rhyme scheme of the last stanza would be AABBC, because "dreary" does not rhyme with any words in that stanza. I am writing an essay and need to talk about the rhyme scheme of this poem, but what would be the rhyme scheme of the entire poem since the last stanza has a different rhyme scheme than the first two? If you need clarifying feel free to type in the comments, I know it's kind of difficult to type out.
