In the 1990s the profession was perhaps more willing to diagnose Asperger's in children than in its existing adult customers! Still, for a girl to succeed in getting a diagnosis would be unusual, so maybe you were "lucky" to that extent.
Unless you are (a) an insomniac and (b) good at emulating the English use of English, I'm going to guess you are in the U.K. in which case the law requires your next employer to make "reasonable adjustments" for you if you declare, from the outset, that you do have a disability (which Asperger's technically is, now). Also I found out not long ago I was exempt from paying Council Tax, by virtue of "severe mental impairment": it's called a Class U exemption I think.
So the diagnosis can be a sort of Get Out of Jail Free card, occasionally at least. Of course, if the employer is not a very nice employer, then declaring yourself disabled won't actually make a lot of difference to the way you get treated, but technically the law is on your side: technically, they can't discriminate against you, and they can't expect you to cope with stuff you can't cope with.
Good luck!
Have the "experts" identified any of your superpowers? And your especially weak points? That might help you target certain varieties of employment, e.g. they said my "perceptual reasoning" and "verbal ability" were astronomical, so if an employer wanted to know what I thought I might be bringing to the table, I'd be trying to sell myself on stuff like that; and at the same time, I'd be emphasizing that I'm prone to sensory overload and my "processing speed" is really slow and I get easily confused and distressed, so obviously the employer putting me on the front desk and expecting me to answer the telephone and engage with the public would be a no-no. If you see what I mean.
