How do you cope?

I'm a new olah, been here three months. Today a missile hit very close to my home with a considerable number of casualties and injuries. Loudest thing I've ever heard, shook the walls of the house and broke several neighbor's windows. I realize I'm lucky to not be hurt but am pretty shaken up. People who have lived here for a long time, how do you deal with this reality and stay sane/calm?
