the worst thing about adhd is when your brain has decided that the only thing that will satisfy it is the one task you're currently doing, and you can tell that it's going to consume the rest of your day and possibly the next couple days. it's an infinite-effort, infinite-time project, but you need to get up and do something else, like, to continue living.
the entire time you're doing that other task, it feels exactly like hobbling to the hall closet with your pants around your ankles because you ran out of TP on the toilet. and god forbid you run into a new blocking problem while doing that, because now it feels like you had to hobble to the front door, pants still around your ankles, ass hanging out, to retrieve the TP from the porch in view of the neighborhood
and every single further step you take away from The Thing You Were Doing, the more it feels like the rubberband connecting you back to it is stretching tighter and tighter and trying to pull you back more and more. and it feels like it's wrapped around your throat.
the inability to "switch gears for a bit" has ruined more opportunities in my life than I can possibly begin to count. personally, i would not have myself be this way! not ideal! there are better ways to be!
