Help

I am a hostage. To my own mind. And its been this way forever, with the dark dreary walls talking to me. They say things i don't. Think things i wouldn't. Two giant walls on my left and right. In front of me is darkness, hungry enough to engulf me. I can't turn around. Day and night. These aren't terms anymore. They are dimensions, used only to determine where i am. Sometimes the darkness in front of me isn't as dark. Lighter shades. Sometimes even grey. But then it just goes back to darkness. Why i am here, i do not know. Color is just thought now. I can't even picture what it is. Whatever.
