Totally. Only that I postponed the thing I had to do for even longer.
Your post made me realize that I postpone because I am afraid of hyperfixating. When I hyperfixate I do things that I don't want to be do, but that have to be done to make them right.
Like I expected, when I finally did what I had to do, I found something that was not right, and spent some additional time on it without being able to let go.
Here is an older thought about it: Could it be that ADHD is an identity thing? Essentially like transsexual but for being and not sex. Hyperfocussing is like wearing a mask, not out of fear of social reactions but from the inability of maintaining my identity. I lost my day by being afraid of experiencing being-dysphoria. It only ends when the fear of the consequences of inaction are bigger than the fears of dysphoria.
