You just need to find a G.P that understands you & has some empathy.
I've kept my current G.P for over 20 years now, she's brilliant. She's not a miracle worker, but at least she listens. I tend not to see her that much now, but I know she's there if & when I need her. I went through a spate of them prior to that, just couldn't cope with them at all.
So maybe you keep on going until you find one you like.
I need one more detail to accept surgery - possibility of booking appointments online, majority of surgeries still requires phonecalling, and that's nightmare.
My current one is very forthcoming, though I've been there once only, I boooked appointment to talk to my GP about obtaining Cancard, he just printed and signed a form stating that I'm autistic, that's what I required, and then we had a nice chat, between 5 and 10min, hard to say, because It was just me rambling about how badly ableist UK society actually is, and what difficulties I face because of it, but he didn't rush me to finish and go
They are building a new medical centre opposite my house. My old GP definitely didn't get it. They wrote in one letter that I "suffer with Autism" and yet were very reluctant to make any kind of reasonable adjustment to be seen with an advocate and were very reluctant to help me get a previous misdiagnosis corrected.
Because of the logistics, I thought I'd change to the new medical centre. But, before I made that decision, I e-mailed them to ask about whether they had any Autism experience. They didn't but really wanted to know about it. Such a difference simple attitude makes. They couldn;t be nicer. It's all about: 'how can we help to make this easier on you?'. Perfect. Can't ask for more.
I'd identify the practices in travel distance and check out their websites. Sometimes they list the specialities that each doctor has. They might include ASD for one of them. Then I'd e-mail them all describing what your main issues are and ask whether they think they might be able to meet your need. Then go with the most positively disposed.
If all else fails, try contacting your local Care Commissioning Group.
