Answer: B) depression
In these lines, the author is showing all the pain that he has over the "fallen star," most likely someone close to him who has died. The poem has a gloomy, sad mood that is consistent with feelings of depression. It is likely that the author is grieving. We can identify this mood through words such as: "moody, tearful night," "the black murk that hides the star," "cruel hands," "hold me powerless," "helpless soul" and "surrounding cloud."
