Pin's fear versus my favorite football player's fear

I’m afraid of cockroaches. When I was 10 years old, I saw a cockroach in a bathroom in my house while I was taking a bath. It was disgusting because it is a large brown dirty insect which can fly. It flew around the bathroom and tried to come to me, then I yelled out, and I was hurry to get out off. After this happening, if I see a cockroach in the house, I’m often nervous and have a nightmare. However, This fear is a normal fear and different from a phobia because a phobia is an abnormal response that somebody very afraid of something which could have a major impact on how they live their lives. One of my favorite Arsenal football player, Dennis Bergkamp, is a case of aerophobia– fear of flying. I used to read his story that he was so severely affected which it meant missing a number of football matches that would have required air travel. Moreover, he also has caught the train or driven to distant matches rather than fly.
