My first panic attack was in 1998. Literally thought I was going to die.
I have had a ton since then - at home or out of the home.
Including at "happy" places like Disney, Universal, SeaWorld, Busch Gardens, and Legoland. Out of the blue.
Had a major one at the Orlando Science Center one day, and a big one in the middle of watching "O Wondrous Night" once at SeaWorld - thought I was going to drop in my chair, had to bolt out of there, felt like a complete ass afterwards, shaky, couldn't eat, etc.
Had a big one once at Hollywood Studios (then MGM). One in Walmart too - completely out of the blue - walking down the automotive aisle. Recently at Target in Winter Garden Village. Another time, had one at home, landed me in the ER with them running EKGS on me; another one at work when I worked for the county years' back (on a completely low-stress Friday) that landed me in the hospital with them doing CT scans on me.
So when she talks about her anxiety, and panic attacks, I literally want to punch her bleeping face in.
