Great chapter....
You are showing the struggles of a newly blinded person very well. We do go through an initial bout of anger, depression, why me. Hate the world mentality. Mine lasted a good year.
I don't know how you researched... We do learn how to count steps in areas traveled most. The moment when sun was felt on arm, very spot -on. This is where a blind individuals other senses become amplified. This is a protection stance your body starts producing to protect itself. Hearing, smell, and touch take on new sensation. Along with taste.
