Getting too detailed, adding stuff, getting lost in my book as it's overflowing
I'm a very non-linear neurodivergent person, writing a non-fiction book. I can't write in order. I write in segments that I feel intuitively where should land and how they will connect. But as I make write, I keep adding details, and I duplicate information because it fits in various parts, and I repeat myself and make things so much more "absolute" that it's overwhelming to navigate or edit.
English is not my first language. And I've never been a writer. I am an artist and write how I paint. Writing has become an important thing because there's no other way to express what I know other than in a book.
Not only I have trouble with writing well single sentences, but the whole book has become a monstrosity, I don't know how to continue. I'm on my eight rewrite (if you can call that because, I've never actually written the whole draft. But I feel the need to start over, to clean and clear the structure and content over and over, and keep making the same mistake—as explained above.
Can anyone advice? Especially I would appreciate from people, who work like me.
