Hospital Visit

My grandmother isn't that well, so she's admitted in the hospital.
My mom (as usual) has been staying there too to accompany and take care of her, but to let her rest, it's my turn to stay at the hospital.
I'm feeling a bit flustered, cause I feel that I'm not good at taking care of her.
Not implying reluctance, but I'm just scared that if I don't do things right, or make a bad decision, I'll just worsen her condition.
Anyway, she's sleeping now, so I'll just do some homework, or just watch a movie.
Probably do homework since I'm too lazy to watch movies (Oh the irony hee~).
Interestingly, my mom has been calling up to check every half hour or so, which makes me wonder why am I here, if she's going to keep on asking...
