As horrible as a panic attack is I would rater have it than this all day high anxiety.

The panic attack raises your heart rate and blood pressure and makes you scared to death,but in less than an hour it's usually over and I feel calmer.

The high anxiety state lasts all day many times and takes till 9pm to subside.

The high anxiety seems to correspond with cortisol,when it drops later in the day when cortisol is lower.

There is always a trigger I think even if it's buried in the back of your mind.
