Me, too. I call it "The Hamster Wheel of Death" when trying to describe it to my therapist.

It usually starts with one line from a song that repeats constantly...then different lines from different songs are added in at the same time...then songs I've never heard...then "chatter"...the list goes on.

I wonder if meds help?? What really helps me is extremely vigorous exercise that requires a lot of thought...like rock climbing or trailing running down a really rocky, treacherous route.
