Which word describes a state of total despair?

The word "abysmal" is often used to describe conditions or feelings that are extremely bad or hopeless, making it an apt descriptor for a state of total despair. When something is described as abysmal, it signifies a depth of disappointment and negativity that can feel overwhelming and inescapable.

In contrast, the other words do not convey a sense of despair. "Promising" suggests potential and hope for the future, which is the opposite of despair. "Innocuous" refers to something that is harmless or not likely to offend or provoke, lacking any connotation of despair at all. "Content" denotes a state of satisfaction or acceptance, which again stands in stark contrast to the notion of despair. Thus, "abysmal" is the most fitting choice to describe a state of total despair.
