The adjective frenetic is another way to say frenzied, frantic, or totally worked up. Kind of how you'd run around the kitchen madly trying to cook a last-minute dinner for 30 of your closest friends.

Sometimes tinged with fear and often quite maniacal, frenetic comes from the Latin phreneticus, meaning “delirious.” The Latin word, in turn, came from a similarly spelled Greek word which, when translated literally, means “inflammation of the brain.” So it's no surprise that a frenetic person looks absolutely crazed and super anxious.
