What adjective or expression can describe the state of a person after a very wearing wait? Like the wait for the results of an important examination,of a decisive political election or of critical medical analysis?
The problem here is that we don't know what kind of psychological factors might be influencing the anticipatory state our subject finds themselves in. The situations you describe would engender apprehension and anxiety in some people, but election results might give rise to positive excitement in others. I would choose a word that you understand to describe the emotional state (x) that you want to attribute to the waiting and then say: "...feeling x after such a wearing wait.
