Disconsolate means too unhappy to be comforted. Nothing anybody says is going to help.
The word contains its own explanation, since being disconsolate means being beyond consolation. It describes people and their appearance, so a disconsolate figure at the end of a platform is a whole picture in three words. Sport uses it constantly for losing teams. It is formal and slightly literary, and the adverb disconsolately usually attaches to a verb of sitting or standing.
