Bone-tired is an expression used to describe a person who is extremely exhausted, fatigued or worn-out. It can be hard to find the perfect antonym for this word; however, some of the best antonyms are refreshed, invigorated, energized, rejuvenated and revived. When someone is refreshed, they are feeling less tired and more alert, while being energized means a person has regained their strength and vitality. When someone is invigorated, they feel lively and full of energy, and when rejuvenated, they feel youthful and revitalized. Finally, when someone is revived, they are brought back to a state of freshness and vitality, thereby implying that the person was once exhausted but has regained their energy.
