Which lines from “The Raven” by Edgar Allan Poe show that the speaker has lost hope of ever being able to move on and recover from the pain of losing Lenore?

ATo the fowl whose fiery eyes now burned into my bosom's core;

This and more I sat divining, with my head at ease reclining

BTill I scarcely more than muttered: "Other friends have flown before—

On the morrow he will leave me, as my Hopes have flown before."

CDeep into that darkness peering, long I stood there wondering, fearing,

Doubting, dreaming dreams no mortal ever dared to dream before;

DAnd my soul from out that shadow that lies floating on the floor

Shall be lifted—nevermore!
