As I've turned into an old woman (which I clearly am), I've discovered patterins (not a typo, just quoting my child) in my world and in the world of those around me. One of the ones I continue to see is that when life is insane, the way out of that external insanity and the way to hold on to some inner peace - is to find your regulating activity that makes it all better.
For some, this is exercise. The world may be falling down around a person, but if he can get in his morning run, he can begin to regain control or, at the least, not lose his mind to the crumbling columns. For some, this is folded laundry. For some, a regular reading quiet time. For some, it is prayer and meditation.
There is a woman on the internet - the fly lady, I believe - who says that if you'll just go to bed every night with a clean sink, you'll be able to begin to form new habits that will save you from chaos. There is something to that - there has to be an external reality to make us all feel better.
There are three things I do when I need to regain control:
1) Pray a rosary.
2) Purge / fill my calendar.
3) Plan my meals.
