Hi there! A colleague of mine referred me to your post. I'd love to have a call and help with advice and coaching to reduce your anxiety of going blind. Since I published the post @ssivark mentioned, I got a lot of emails from developers who were afraid of going blind or who were actually like yourself and were going blind, so trust me when I say that you are not alone and people like you have pulled through. Since you value showing up and being independent, I'm certain you will pull through, too.
Please reach out to me on my website (https://www.parhamdoustdar.com/). I'd love to help.
