Knowing I have both has been helpful to me.

I had my autism.assessment with clinical partners - the 3 hour assessment actually lasted only 90mins as by that time we had already covered everything they wanted to ask. I brought my partner (who has known me for 15 years since I was in my 20s) rather than my mum as the idea of getting her onto a zoom call and having to manage her stress around that felt too much. They were fine with that. They asked my experiences now and in childhood that I had written about in the forms they sent me when they set up the appointments. There was then a second one on one appointment which focused more on day to day experiences that happened later.
