My most frightening moment was the time that my older brother, his friend and I went exploring through a cave at Devil's Den State Park. I think I was 11 at the time, and my bro and his friend were 13. Anyway, there were only two flashlights between the three of us, and I got to hold one of them. After a while of exploring, my brother tells me that his friend should hold the flashlight instead of me, so I gave it to him. We walk a little further in the cave, and then suddenly the two rushed ahead of me and left me in the dark. I couldn't see anything, and I started to panic. I also started to hyperventilate.

Anyway, there was a group of other cavers who were a little ways behind us, and when they saw me, they brought me back to the entrance of the cave and made sure I was alright.

So that's probably the most afraid I've ever been. I've never had a panic attack before or since then, and I never want to experience one ever again.
