Scared of heights.
In my culture fear is a bad thing. If one shows fear, one is also showing an emotion. But I have always been afraid of heights. Not space level heights but about 50 yards above the ground heights. They make my ankles feel like they are made of rubber. I was always told not to look down but I couldn't help it.
I finally got rid of my fear one day when Star Fleet command told us to come to New York for a meeting with the media during our shore leave. Jim and I had to take the subway. Even after 400 years they still worked. I started to feel scared while the train was above ground. I meditated and tried to relax. It did not work. But he saw that I was scared and he grabbed my hand and held it tightly. Now when I feel scared of being up high I remember his cool hand in mine and rid myself of the fear.
