@ThreeBeanChilli I think that sounds like you've made good progress. Talking to someone else who points out things you don't realise yourself is a great way of helping you understand.
I did the AQ50 about 3 times. Things I initially thought didn't apply, actually really did once I'd thought it through. Where I needed to, I made notes at the side. I've said this before, but the question "are you unaware you are talking too much / boring people?" I put something like I know I'm doing it, but I absolutely can't stop.
I don't know if you've ever watched Atypical (show on Netflix) The protagonist says people don't think he realises when they are picking on him. He does, he just doesn't understand why.
I think telling the GP that what you find is normal makes it hard to complete these questions, but they will still expect you to have had a good go at it as a pre screener prior to opening the door to assessment.
I don't think there's anything that really explains what the questions mean as such. It's something that can be delved into deeper during assessment.
I wrote pages of info (no surprise there from me!) but picked out a few choice statements to give to my GP such as:
Only ate 4 different foods as a kid.
Obsessive about being on time or early.
Don't always get jokes.
Talk far too much or not at all
(Often monologue and interrupt)
Can't touch certain things (newspaper, bricks, put my hand in a crisp packet)
Quite obsessive interests (Aircraft, Birds, Farming, Medical Information)
Needs and gives massively detailed information.
Before I knew it, I went from wondering if I was Autistic to it being extremely bleeding obvious.
