Some nights, she tosses and turns, unable to catch forty winks. On others, she cries herself to sleep.
It is the long nights that are the toughest to get through for Ms Grace Koh, 29, who is a caregiver for both her aged parents.

Last month, her father also fell in the toilet and sustained a brain injury. He is undergoing rehabilitation in a community hospital now.
