It turns out I am one of the who knows how many adults, especially female/raised as female, with ADHD. I have the hyper focus, difficulty sticking with and finishing "projects" with deadlines meaning nothing, not being able to "quiet" my brain or "calm down", and the search for the emotional fix*. Because I was also a "quiet" child and did generally okay in school, gifted in some subjects and outright failing others, no one bothered to see if I had anything aside from a generalized "learning disability".
So the reason I never know if or when I'll finish any doll projects is totally my brain, nothing to be ashamed of, and if you see it in yourself or loved ones look in to it because it would be nice if you could find some cognitive ways to deal with it. I have managed to get better at some things and have an easier daily life. You can get your brain to cooperate with scheduled resting times.
There's no shame if your totem is a squirrel or some other small mammal.
*Personally my frontal lobe brain injury and the associated medical treatments have left my ability to feel emotions skewed but I remember what it was like.
