Try and keep yourself stress free. I don't know if these forums are helping your issues any to be honest with you.
I've read recently that a little stress is good. We need it.
Panic attacks are pretty random aren't they?
I've had 4 in my entire life
weirdest one was on a plane
(I used to fly about 10 times a year so not an unusual experience
but one I found mildly uncomfortable being a little claustrophobic)
Suddenly found myself drenched in sweat, heart thumping, nausea,
dizziness. Must of looked dreadful because hostess asked if I was OK.
Got to the toilet washed face, dried myself and calmed down.
I've no idea why it happened on that flight and not any other.
Just suffering from regular incidents like that must be stressful itself.
Sufferers have my sympathy.
