Not anxiety unless I've had it for 10 years, 15 now.
Also, last time I remember it happening was on a weekend in the middle of the day, had nothing to worry about. I just felt pumped full of adrenaline
(not like anxiety).
another poster on a medical site uses vertigo medication to stop the fast feelings described and that i experience. not sure if that would work for
everyone. it sounds like an combination of anxiety, ruminating thoughts, worry, etc...zoloft has helped me with this and other stuff, but i quit
because it made me so complacent.
