+Why does your sufferer behave in this manor? She feels unsafe. Following the map meticulously is how she attempts to feel safe. Safety is a concept that is not understood by many people, and unless you've been in the position of constantly feeling unsafe, you don't know what this feels like as you simply can't.
Safety is a basic human need that is taken for granted by many/most. There is something called the pyramid of human needs. At the bottom is food/shelter/water. Right above this is the need for safety.
@Solara - I think you're absolutely spot on, unless you've experienced the terrifying sense of having your life being under threat you really cannot empathise with this constant feeling of existential unsafety. I wouldn't have Before Trauma. I was Mrs-take-it-all-in-her-stride!
Maslow's triangle is very useful indeed, especially for explaining to clueless professionals. I had been at the top for years, self-actualised, running my own business...and then along came the stalker....as time went by I was scrabbling to even get on the food and water rung. Literally was without food for weeks at one point. As I write I am living day to day, not knowing where I shall be living next month. My way of making lists is to document everything as meticulously as possible.
