"I don't even know how long she's been gone. It's like I've woken up in bed and she's not here... because she's gone to the bathroom or something. But somehow, I know she's never gonna come back to bed. If I could just... reach over and touch... her side of the bed, I would know that it was cold, but I can't. I know I can't have her back... but I don't want to wake up in the morning, thinking she's still here. I lie here not knowing... how long I've been alone. So how... how can I heal? How am I supposed to heal if I can't... feel time?"
