If something makes her afraid, simply forge on (or turn around and leave) very nonchalantly, paying no attention to her fear response.
When she calms herself, then is the time to praise her. Not overly done, just a "See, that wasn't so bad!" kind of happy tone.
By "comforting" her when she's afraid she'll learn that it's okay to be afraid and show signs of distress.
