I'm very sorry for your difficulties. Is this condition in both eyes? I'll assume you have this in both eyes and it is probably called optic neuropathy or optic atrophy. The best thing you can do is get a good second opinion and seek the assistance of a "Low Vision" specialist. They can train you to see and feel the world more effectively.
Best wishes,
