I was afraid of getting into a car accident, breaking a bone, or stepping on glass or anything sharp. Basically, things that could physically hurt me. I wasn’t afraid to travel in a car, and I did sports, and sometimes walked barefoot, so the fears weren’t overwhelming.
I still have a fear of throwing up, and the dread does control some of my behaviors. As a kid knowing that drug withdrawal or too much alcohol can make you throw up was a huge deterrent for me. I never tried any drugs, and I can count on one hand how many times I drank alcohol while in school K-12, and it was never more than a drink. As an adult, I still don’t drink, and also if I have any doubt about food going bad I throw it out.
Lastly, fears about biting and stinging insects was more extreme when I was younger, and also seeing a roach was scream worthy.
