Has anyone analyzed this poem beforE? i need information on rhythm, rhyme, figurative language and theme!!!

Those seem pretty easy. What I can't figure out is why every copy I saw on the internet had the "it's keeping" error intact.



I have experienc'd
The worst, the World can wreak on me--the worst
That can make Life indifferent, yet disturb
With whisper'd Discontents the dying prayer--
I have beheld the whole of all, wherein
My Heart had any interest in this Life,
To be disrent and torn from off my Hopes
That nothing now is left. Why then live on ?
That Hostage, which the world had in it's keeping
Given by me as a Pledge that I would live--
That Hope of Her, say rather, that pure Faith
In her fix'd Love, which held me to keep truce
With the Tyranny of Life--is gone ah ! whither ?
What boots it to reply ? 'tis gone ! and now
Well may I break this Pact, this League of Blood
That ties me to myself--and break I shall !
