Question

Which lines in this excerpt from Edgar Allan Poe's "The Raven" clearly depict the speaker’s grief over the loss of Lenore and his frustration with the raven?
Ah, distinctly I remember it was in the bleak December,
And each separate dying ember wrought its ghost upon the floor.

And the silken sad uncertain rustling of each purple curtain
Thrilled me—filled me with fantastic terrors never felt before;

"Leave my loneliness unbroken! quit the bust above my door!
Take thy beak from out my heart, and take thy form from off my door!"

Open here I flung the shutter, when, with many a flirt and flutter,
In there stepped a stately raven of the saintly days of yore.

For we cannot help agreeing that no living human being
Ever yet was blessed with seeing bird above his chamber door,

Answer 1

"Leave my loneliness unbroken! quit the bust above my door!
Take thy beak from out my heart, and take thy form from off my door!"
shows that the speaker is in a great amount of grief and wants to be left in it, without being disturbed and the disturbances are frustrating him.
