CelticZebra - I was definitely having the flight or fight reaction. It was so bad. Last night, I was too exhausted to even be anxious.
Morning of day 3 for me and still anxious, but it's not as bad as it was.
This morning I did notice a bit of chest pain, now i feel like that's another issue i have to worry about.
At the moment, i'm focusing on my breathing. Which is helping.
