I think we're going to see some big changes in how ADHD /Audhd /autism is defined and categorised in the next few years.
I don't know whether this will be autism broken into distinct sub-types, or ADHD becoming an aspect of autism, or some other division or combination.
In the meantime I'm holding onto these labels lightly and only referring to them in as much as they help me understand myself, and find community of like minded people.
The traits you recognise in yourself are a real phenomenon. Unless you think they're caused by something that requires treatment or managed in ways other than what you're already doing, you can't really go wrong with exploring this new aspect of your self-realisation.
You might figure out an explanation other than Audhd, or it might start feeling like a helpful label.
For myself, the more I learn about it, the more Audhd fits my experience.
