I'm posting on here as much as anything just because I feel like telling someone and won't be able to tell my partner until I see him in person (he's been away this week)
I had an assessment and have been diagnosed as autistic. This was a full assessment after a screening questionnaire and then phone consultation, and the assessor explained at the start that she had enough evidence from the first two to be very confident about a diagnosis.
If anyone is unsure about being assessed and what it would bring, something I found really helpful was that at each time we discussed something where there was difference, the assessor talked through some useful strategies to try in future. Strategies which were realistic - eg along the lines of 'X is happening because you're not using body language other people would understand to convey that you've had enough. That body language is subtle and hard to learn, so I'd suggest you use words instead. Phrases you could try include....'
I say this as someone who is very accustomed to masking, and in a profession that has literally trained me to talk to people. So Im used to reflecting and learning, but still found a lot new to learn from this.
Although after researching it enough I was quite confident that I was autistic, I still feel a bit weird having it confirmed. One area that I'd always doubted about were sensory issues - I definitely don't have these in the way a lot of people describe - but there are other aspects that I met very highly, and there only has to be a certain number of sub sections met to meet the overall diagnostic criteria.
Happy to answer questions about the process if I can be of help to anyone else, I know I read a lot on these boards before I took the plunge and started the process (I went private, which I know I was very lucky to be in a position to do - I wish I hadn't had to spend that money as it's still a lot, but I had no faith in the local NHS process where I live)
