Because attaching to an unstable spectrum of symptoms and making it an essential cornerstone of an "I" is a terrible idea, no matter who you are. The "I" is just as formless, slippery, and unstable.
Secondly, when we do attach, we now have a shield we can use to abdicate responsibility for, well, the duties of being a human in a society. I've had to remind people who have thrown their hands up to exclaim, "I have ADHD!" that hey there buddy, so do I, but I still have to live my life right here in the same society/job/relationship they do.
Where diagnoses like ADHD are useful is as frameworks to understanding your own symptoms, but there's no reason to pull them in as part of you, and I've seen a great deal of harm done in our generation by people insisting on playing out their identity fantasies.
