It is not as if I feel terribly anxious. Just kinda constantly
restless. And not really able to enjoy life. I constantly think
"Ok, I need to get over this appointment first. Then I can live
my life again.".
Yeah, this is totally me.
As other posters have noted, just noticing it without judgement is a thing that helps too. Practice noticing it without beating yourself up for it. (Mindfulness, essentially)
I think for me it's more of an "executive functioning thing" than an "anxiety" thing?
Like, I'm not even worried or scared or dreading. I'll just keep thinking about it. It feels very adjacent to ADHD.
Part of why I'm sometimes hyperfocused is because my mind can't stop thinking about the unknowns. Where will I park? Or should I Uber? How will traffic be? Is my neighbor available to dogsit? what will I wear? etc.
So often, resolving those things is the biggest boost. If I can't answer the unknowns, I can sometimes cope by coming up with a Plan B ("I'll take a spare outfit in the car, in case I'm overdressed") or just resolving to leave early ("Traffic is too hard to predict, so I'll just leave a full hour early and have a drink at the bar while I'm waiting for the event if I get there way too soon.")
