Thank you for the lovely kind words about KNIFE (I'm honoured and touched that you thought it good enough to share with a friend who is living with a disability!) and your other thoughtful observations from experience.

I think this is especially excellent:

The thought that disabled people live unhappy lives didn't come out of the blue; it's caused and enforced by the unrealistic portrayals in literature.

Yes, yes, a million times yes. Thank you for saying in two lines what it took me two hundred. :)
