The thing is that you shouldn't really care about the details of these small functions until you for some reason, need to. At a high level it's easier to understand stringing together a bunch of small functions and assume how they work. If you have ADHD it seems like abstracting away the details in the small functions should help you, but it seems like you aren't able to ignore the details of how each small function works even when in context it doesn't matter, which is where it hurts you.
