I fear cockroaches. Louisiana produces some that are pretty big that can fly. At work today, while doing Land Survey, I had to flip over a manhole and clinging to the top as it flipped over were about 20 large cockroaches. My skin was crawling, my heartrate was flying, and I felt just fear.
Injections bother me because I had to get shots in my eye as a kid to numb it for stitches, but I didn't react as badly when I found a syringe on the side the road.
I really contemplated quitting. It just scared me that much. I could also hear them clicking along the road as they ran from the birds that wanted a quick meal. It sucked.
