I had all the characteristics of a human being - flesh, blood, skin, hair - but my depersonalization was so intense, had gone so deep, that my normal ability to feel compassion had been eradicated, the victim of a slow, purposeful erasure. I was simply imitating reality, a rough resemblance of a human being, with only a dim corner of my mind functioning.
