Worried and Waiting

This is a horrible waiting game. My grandmother has been not doing good for a while. She is very old so these problems that have come up as of late are telling us that it could be any day now. Is it today or is it tomorrow?.. but days pass by. Now she doesn't eat and she can't even drink water and she can no longer talk as well. She's just... there. So we wait. I got a text from my cousin earlier telling me that she might not make it through the night. So we wait. I feel so much apprehension every time the phone rings or I get a text or one of my cousin's update their facebook. Right now the hubs is at work so I feel really alone. I've been trying to occupy my mind with mindless tasks. Burning mixed CD's for my uncle, playing Left 4 Dead, taking a shower that I don't really need. I've been trying to get a hold of my mother since 6pm. Calling and calling her cell but she never answers. I even called my stepdad's phone to no answer either. This also makes me uneasy. I cannot think of any reason why she wouldn't answer. I can't think of anything she might have mentioned that would keep her occupied for these past 4 hours so i'm kind of starting to get worried about her now. The hubs has the car so I can't drive over and check on them. Ugh, I hate to worry.
