If you can do something about it - do it! Here is the part where you stock food, water, fuel, heating sources, pack emergency baggage, plan routes, etc. I don't know where you live but keep in mind that the worst scenario (all-out nuclear war) isn't the only one - a 'regular' war is more likely. It will also require more actions since in the case of nuclear war you might not have a chance to react.
If you cannot do anything about it - just stop worrying about it! I know it sounds easy and I know that it isn't. But in the end worrying about things you cannot change is pointless so we should try to avoid it. I have found meditation useful in calming my mind which has been churning war thoughts the better part of the last 2 weeks.
