Alot of anxiety works like this .
Anxiety really is just another addiction weather it is a thougt or a symptom such as a buzz . Once your remove your focus you dont notice it .
Look at it this way you may be in your room , feeling like crap and focusing in on something and dwelling and then someone you like rings or comes by and you get yapping and
you forget all about it .
When they leave you may think whats missing and remember it and start thinking about it again .
With my driving it worries me more when i am away but now i go and have increased symptoms while in car and thinking and then while i am away doing things i am fine . As soon as i get back in the car i start thinking and it returns . Another one to work on
Distraction is one of the best things to learn with anxiety . Hard when your board driving
