I think it's great that you treat her in such a humane way. I'm sure it's not always easy. However, i think if you gave her a book she would just take THAT as an insult. It seems a high IQ just gets people into trouble sometimes. I think of our favorite author, David Foster Wallace and how his genius didn't do him any good (as far as longevity goes). Maybe it's better to just put your efforts into your own recovery? That might be best for her too, so you can continue to support her in your own gentle ways.
