Shadow of Death

I don't know how to describe my feelings now... seeing loved one dying day by day is more heart-piercing than anything. he could pass away anytime, sometimes he seems ok, sometimes got to be well prepared, our mood is like roller-coaster... basically, there's no hope that he will recover or wake up anyway... it's just how soon he will be leaving us... please pray for my mum's family. need God desperately. Thank you.
