Hello Clarkie, and welcome!
With 'high-functioning' autism, if you think you have it,the chances are that you do have it. I have it, and eventually got a diagnosis of "on the autism spectrum... but does not fully satisfy the criteria". Criteria for what? You either are or are not on the spectrum. There's no half-way house. I've been struggling to get a more detailed and accurate diagnosis, for this vague and ambiguous diagnosis is of no use to anyone really, and I'm on a waiting list. At least it's satisfying to know that I'm officially on the spectrum.
The reason for this poorly-worded diagnosis is that the ADOS test was used on me - a test designed mainly for young boys. and that the psychologist lacked appropriate training. As an adult female, he was clearly unfamiliar with the female presentation of Asperger's/HFA. I satisfy the criteria for that perfectly!
So please make sure that :
a) Your GP doesn't fob you off simply with anxiety or depression (which happened with me at first)
b) He/she refers you to a clinical psychologist/psychiatrist who is experienced in the female presention of HFA.
c) They may claim that they are, but insist on proof. If you already have read up on the condition, test them on their basic knowledge. It's your right to have a suitably qualified professional.
If you don't do this, you'll suffer as I've been doing for the past few years. They really do need to get up the mark in this area. Misdiagnoses and underdiagnoses of females, especially adult women, are rife and can cause decades of unhappiness and confusion. e.g. when thousands of women are misdiagnosed with BPD/EUPD, the usual bin where too many 'experts' routinely dump difficult (for them) cases.
If there's anything at all you want to know about female type autism, please ask me.
