I hope things work out ok for you, I can imagine that it must be very scary. As you asked for positive stories:
I have a friend who only has one eye, and only about 15% vision in it, so she is really quite severely visually impaired. This is following early childhood cancer, so she's functionally never known different.
She lives in a lovely home with her husband (who is also visually impaired, although not as severely as she is) and their toddler. She works part time as an activity coordinator for the elderly, having achieved the qualifications to do so with support from the college. Her phone and laptop have software to make text big enough to read, and she's able to do any household task. She can't drive, but she cycles, although not in unfamiliar areas. The house needs some work, and while they're getting professionals in for the complicated stuff, they're doing the simpler decorating jobs themselves, sometimes with help from friends.
Her husband works full time as an IT security consultant. His employer have set up his workstation with adapted software so he can read his screen properly, and provide him with train and taxi transport if he needs to travel to a client (his colleagues would normally drive).
They do almost everything other people would do by themselves. The only thing they frequently need help with is transport to unfamiliar places, because they can't drive and they can't read signs or directions on a train station or the front of a bus. They make that work with the use of taxis, or lifts from friends.
It's not always easy, because the world is of course set up for seeing people, and I don't want to pretend like it is - but really, my friends lead very ordinary, happy, and successful lives. It is absolutely possible.
