Hello! I have Type I Usher myself and my vision tanked when I was 27 (~8 years ago). I'm a writer, so I can't give you much programming advice but I've been through the gamut in terms of technology and life changes. I'm happy to share what has and hasn't worked for me. My email is in my profile.

I do want to say one thing, though: It absolutely sucks at first but you'll adapt. One day at a time.
