Also the body can apparently become used to high levels of anxiety. Read the recently but of course, can't remember where

. I was told in therapy in the 1990s that no one can have a panic attack that lasts for more than 20 mins. because the body can't sustain such high levels. My longest panic attack was nearly 3 days

. We were out in a Theatre with friends and the nausea began. I had to leave, felt really really ill on the way home and shock so badly that the bed moved. Not easy, it was a 4-poster

. I couldn't eat. Couldn't get out of bed, enjoy my bath ....... I can't remember how it stopped but I do remember the physicality of that night.
All my therapists and psychologists explained the correlation between flight/fight responses, but that didn't stop the anxiety taking over. Still doesn't when it strikes. Something to do with the auto ? reaction [must look it up]. I know it's natural. I know why it happens. But that doesn't stop it happening becaseu the physical feelings overwhelm me.
That early morning fear was pre-hensile, anytime after 3.30 and I would be deeply fearful. I think I was afraid that I would harm myself

when alone. Because I was so fed up with it all. I even had nightmares so there was rarely a break for me.
It is unlike singing on stage, interview nerves, driving test nerves: because I suppose that I knew that once I got going, those nerves would settle.
