“A diagnosis is intimate. It is a conclusion. If it is given after years of uncertainty, it can seem liberating. It affirms that all the worries were not unnecessary, that there was, in fact, something wrong; it proves that your own perception of reality is the right one and that you can be trusted. It can put one at ease. If a diagnosis describes a progressive condition, it can also be a source of unease. It conjures images of the future. It is a road map to a place you don’t want to visit. A diagnosis has its own gravitational field. It can shape identity, like other weighty concepts—gender, sexual orientation. One who has never been diagnosed is free without knowing it. What happens when a diagnosis vanishes suddenly? Something is gone, but it was never there, and that which remains is the same as before.”
