Oh dear. That sounds like something from my nightmares. I have spotlight nightmares all the time. I'm not sure how I'd have dealt with it. If you managed to not panic, then you probably did better than me.
I'd have probably tryed to kick off the footy socks and remembered my purple toenails. Then I'd have slapped myself in the forehead and run away. All eyes on me only works for me if I have prepared myself for it. I feel for ya.
