There is also an Intro which was my newbie post. It is worth starting there first and then go to part I. Click on my aj33 to find my blog list.
I can't help to wonder how hard it would be for oneself to find "introspection" while being inflicted with catoptrophobie! (I read a few of your posts. I like your style) Hey, as far as the migranes go, go to COSTCO and buy organic frozen blueberries and eat one cup a day. Don't stop doing this! That will put a stop to those issues soon. Powerful medicine those there blueberries.
I am not totally sure if you mean with catastrophic phobia, that someone has the tendency to exaggerate fear and bad happenings? If so, (but with caution, because I do not know enough about the person) I wold rather encourage mindfulness techniques. Introspection like in "exploring one’s feelings and thoughts" could augment bad thinking patterns (like catastrophizing), mindfulness techniques would more encourage to not explore but notice the thoughts and feelings (without further exploring, but an accepting mindset). But as said above, I am not sure, if you perhaps meant the same :-D
And thank you for the blueberry tip, sadly no blueberries here … only some weeks in summer
