This cockroach-like existence is cumulatively intolerable even though on any given night it is perfectly manageable. "Cockroach" is of course an allusion to Kafka's Metamorphosis, in which the protagonist wakes up one morning to discover that he has been transformed into an insect. The point of the story is as much the responses and incomprehension of his family as it is the account of his own sensations, and it is hard to resist the thought that even the best-meaning and most generously thoughtful friend or relative cannot hope to understand the sense of isolation and imprisonment that this disease imposes upon its victims. Helplessness is humiliating even in a passing crisis—imagine or recall some occasion when you have fallen down or otherwise required physical assistance from strangers. Imagine the mind's response to the knowledge that the peculiarly humiliating helplessness of [amyotrophic lateral sclerosis] is a life sentence (we speak blithely of death sentences in this connection, but actually the latter would be a relief).-- from Night by Tony Judt.
