A phobic person is afraid of something right? Well, you could write about why they act that way... I mean triggered that phobia or what was the cause of why they act that way. First, pick the phobia you want to talk about. For your intro write a dramatic thing about that phobia and what it is. Then for your first paragraph write about what causes that phobia and how many people have it. For your second paragraph search up a person that has that phobia and what may be the cause of that person getting that phobia. And I got no idea how to do the conclusion.
