Well, I would strongly recommend starting with the AQ50, and seeking an assessment.
You said you know you're not ND, but I mean, you can't know that if you also tick off a lot of boxes that meet the criteria for autism and/or ADHD in one post.
BAP isn't a diagnosis. It's a clinical descriptive term used to explain when certain characteristics and traits may overlap with the diagnostic criteria.
It's not something you can be diagnosed with, it's just a research and clinical term.
If you were to go for an assessment the outcomes would likely be: Diagnosis of autism spectrum disorder, not enough information at present but share clinical traits (usually used when there's not enough evidence through the history gathering section of the appointment or where they're unsure as to whether there could be another underlying cause like early childhood illness that could impact development), or no diagnosis of autism spectrum disorder. Sometimes other diagnoses are made either on top of an autism diagnosis, or instead of an autism diagnosis like cPTSD.
I've never met another autistic person like me, despite living in a house full of autistic people. I also don't feel autistic. I don't wake up on a morning and feel like I am more autistic one day than I was the last. The same way I don't wake up on a morning and feel like a woman. I just am autistic. It took almost 30 years to get a diagnosis, because I didn't realise that the reason I'd accrued 40k of debt was because I was extremely gullible and being financially abused, can't understand peoples intentions, or that I didn't have many friends because I struggle to show interests in what other people are doing, and lack emotional reciprocity, or I didn't realise there was a reason I was paralysed when being asked to switch tasks.
One of these being that while working in a contact centre, and my job being switched from a webchat based role, to a call centre based role due to a company restructure, swapping from talking to writing up notes and back to talking was due to delayed processing and executive dysfunction. Or struggling with the instant expectation to conjure up words when conversations deviated from a script I'd created in my head. - One of the RA I was recommended by OH was that my employer could use some software that writes my notes for me, which would have been an immense help, though wouldn't have helped me with the mutism from script deviations, in a job I didn't actually sign up for, it was foisted on me by a business change. Also caused a lot of uproar from colleagues I thought of as friends because they also wanted access to that technology if it was available to me.
I just thought I was a very naive, anxious person, with personality flaws that I could work through with therapy, and that it's normal to feel so anxious you wet yourself a bit on public transport, and I thought everybody felt the same as I did and was just much better at hiding it.
When I'm not in those situations, I don't even feel disabled. But the truth is I am disabled, I am just extremely well socially supported and structures have been built around me in my personal life to prop me up and reduce the chances of me encountering disabling scenarios. You're probably not like me at all, but I'm probably also not like the people you mentioned in your post either, because no 2 autistic people will have the exact same struggles. The thing we will have in common is that our struggles will meet the threshhold for the triad of impairments, will have, in some capacity even if mild, been present since childhood, and there will be no other clinical explanation for the traits present.
So I would recommend you seek an assessment, because the things you've mentioned in your earlier post could indicate you meet the triad of impairments, but that would depend on if there's a clinical reason behind your preferences or not.
