If you are ‘disconsolate’ about something, then you are more than just unhappy. This formal word implies that you are so upset that you cannot be consoled or cheered up. It is generally characterized by silence and deep, melancholic introspection; like you’re lost in your own world. Typically this is the temporary result of a tragedy or crushing disappointment.
