For my diagnoses last year I did a lot of tests, 26 in total also to exclude some other disorders. Now my psychologist is trying that I get financiell support, cos I'm not able to work properly (due to overloads, concentrationproblems, anxieties eg.) and she told me, that they might ask me, why I haven't been diagnosed in childhood. So I searched some articles in the internet about why girls/ women often remain undiagnosed in order to show them. She told me, it's not a good idea, because NT-people might interpret it as me trying to play autistic. She told me just to be the way I am.
