The key

The doctors look at me in dismay.
'You tried to kill yourself because of a book?'
I want them to leave me alone. I didn't try to kill myself. I killed myself and I was dead. I was one step away from knowing what's on the other side. I saw the door, the key and the book.
I chose the key. A natural choice but the wrong one. I was sent back. Then I knew the book was the real key to the knowledge beyond that door.

Next time, I'll choose the book. As soon as they leave me alone.
