Dear L.,
A mind B-complex dificency will aggrevate any fears and compound the situation. Get your daughter on a very good multi vitamin and then get her on vitamin B1 100 mgs a day. You vcould do the multi vits twice a day or just in the morning. This should help a lot.
The other thing is have her look at these places and tell you about the fear. Go over lots of examples of people being hurt at a place but many thousands of others not being hurt. It is a matter of communicating it in a way that she can fully grasp.
The vitamin B1 that I recommended really helped my daughter with nightmares. It took some time, but it worked.
