Garth Stein said this quote

Did he understand, as those interminable minutes ticked by, that being alone is not the same as being lonely? That being alone is a neutral state; it is like a blind fish at the bottom of the ocean without eyes, and therefore without judgement. Is it possible? That which is around me does not affect my mood; my mood affects that which is around me. Is it true? Could Denny have possibly appreciated the subjective nature of loneliness, which is something that exists only in the mind, not in the world, and, like a virus, is unable to survive without a willing host?
