What do you do?

So today my dad and I went into the hospital to visit Grandma. She didn't look as chipper as she did yesterday. She seemed kind of out of it. She hasn't slept for 2 days, and she doesn't eat becasue when she does she gets sick from all the pills. So I say to myself WHAT!!!!
Dad and I call the nurse in and say hey, you need to change the pills you are giving her. They are making her sick and she needs a different sleeping pill the one you are giving her isn't working. Sometimes I wonder if these people really went to collage.
I have told them all that they had better take care of her, that she means everything to this family.
While I was there today they were talking about sending her home tomorrow. I was excited! But then they say that if she isn't doing well they are going to send her to a rest home. I wanted to cry. Thats where old people go who can't take care of themselves. Not my grandma!
They think it would be best at least for a week until she can start walking and doing stuff on her own.
My dad called me a couple of hours later, and after talking to his Aunt Joyce who had the same thing done. She said it is the best thing for her. They will have her walking in no time.
I just can't even think about her in a place like that. Just talking about it makes me cry. I am such a baby. She deserves better than that. Even if I have to move in for a week I would rather do that than have someone else take care of her.
She means everything to me.
SO FRUSTRATED!!!
