Unendurable Stillness

I read a book recently (The Witch of Portobello, by Paulo Coelho) in which the protagonist was described as someone who had trouble with the "blanks spaces"-the pauses, the parts between the letters and the words, in life. She was constantly restless, always looking for something else, someone else, another answer, another question...anything really to avoid the pauses in life because she found them crushingly, overwhelmingly empty.

I realized I have and have always had the same issue and that this is the major thing I need to work on at this point in my life. While I'm not entirely sure how to go about this I think the first step is to determine why I find the blank spaces so crushing and stillness so unendurable.
