It is definitely worthy of celebration. As a person with a disability myself, I use a wheelchair, It can be disheartening. There are so few characters, in either books, movies, or tv shows that have disabilities of any kind. And I've only read a few books actually written by a person with a disability.

I am currently in the process of writing my first book. I have quite a few disabled characters. What I plan on doing, eventually when it is "done" is to find other members of the disabled community to ask for a read. It might be something you'll want to do too.

Anyways, with most disabilities, the way it works out will be different for everyone you ask. So don't worry too much on producing a situation too much like your own. It's your book, after all.
