Yes, and I was very embarrassed!
First time, I fainted in school assembly just as the lines were leaving. I had stuck out my arm to see if the line behind me had left and was promptly told off by the girl I touched, fainted and as I did so I heard her shout out to the headmaster I had fainted! ?
A few years later, I had an asthma attack - before I knew I was asthmatic - in pub toilets and rushed out for air.
A lovely off duty nurse helped me.
And just a few years ago, a flaming panic attack as I got caught in a Christmas crowd and could find my way out - again, was helped by a lovely lady!
Did you climb trees when you were little or were you a city dweller?
