Bone-tired

Having escaped from the Lac-house in Varanavat after setting fire to it, when the Pandavas, along with their mother Kunti, reached across the Ganga, they were bone-tired and thirsty.

However, if you are like many college students and day after day you don't get sufficient sleep or you live under constant stress, you are likely to feel unrelentingly worn out and bone tired.
