Consider: in 1914 or 1939, if the present level of media coverage had been in existence, wouldn't you have felt nearly the same emotions?
Trouble has existed for humankind since the first protohuman thought of an axe, or a spear. This is nothing new. It was MUCH MUCH worse during the 1950's and 1960's. Consider those living during the Cuban missile crisis. That must have been hell. Consider those fighting in Vietnam. That was hell. Consider the Arab-Israeli wars of 1967 and 1973.
Chill out. Things are not as bad as you are seeming to see them.
