tossing metal coffins

I woke up to light and silence for the first time in I don't know how long. I'm in a small room with a hard backed chair, a dim lamp and a computer. I don't know where I am or who has me, but I am glad to see light again. I'm guessing it is the 5th or 6th of January. I've been held for 5 or 6 days now with no light; loud, non-stop metallic scraping... jarring me to the bone. The 'room' felt to be about 6 feet wide and 5 feet tall... freezing cold. No blanket, no bed, I couldn't stand, I couldn't sleep. A small door would open near the corner for someone to toss in a piece of bread and a bowl of water every so often. I could hear people talking, but the metal scraping kept me from hearing what they had to say.
I never thought a room tall enough for me to stand in with a chair, lamp and computer would make me so happy. And the silence. How I have wanted silence. Beautiful. I still don't know where I am, I don't know why I'm here, and I don't know when I get to leave, but this is so much better than it was. I can see where the wires come into the room for this computer... maybe I can make the hole bigger. The room seems to be made out of metal as well, but banging on the wall gives a deep hollow sound. I don't think the walls are thick at all. Hopefully there is something on the other side.
If you are reading this, I hope I can find a way out of here. I want to tell you how to find me, but I don't remember anything past leaving the New Years party. A good night apparently didn't end well. Going to try to make a bigger hole. More later if this thing isn't disconnected.
