I remember reading an amazing short story/novella (at least 15+ years ago) that focused on a universe where it has been discovered that the vastness of space drives the pilots of spaceships insane over time. The only people that seem to be able to withstand this are people with mental disabilities; they are described in the story similar to being on the spectrum of autism, if i remember correctly. They are then trained to be the pilots of these spaceships, since they’re not affected by the vastness of space. The big reveal in the story, as it was told through the eyes of one of these pilots, was that, sometimes, these pilots would be 'healed‘ by their exposure and 'wake up‘ (i.e. overcome their conditions).
Does anybody have an idea what story that could be?
