I know with Ipods etc. it’s a trifle outdated to be employing a record analogy here however it works well as an example a key purpose regarding anxious thoughts.

The same one line would play over and all over again ad nauseam till you picked up the needle and moved it past the scratch.
Anxious thoughts are bit like this. you may be happily going regarding your day and then one thing triggers an anxious thought.
