I used to be very 'political'; a member of several conservative political internet forums, read the news "religiously", wrote letters to the editor, and “soaked up” all the news I could. Then I had a couple of heart attacks (seriously).
While I still keep up with events, I now do it under my terms – almost exclusively internet news sites. And I’ve narrowed my political activism almost entirely to those things that have a spiritual impact on my church, my family, my friends and me. My stress level has dropped dramatically.
The thing you will get from the ‘nightly world news’ is just that:
WORLDLY news! You have humanists reporting on humanism. You have humanists reporting what they believe you need to know in order to carry out their social engineering experiments,
and they are experts at making you feel guilty about things which you have no control over.Jesus said “You will always have the poor…” Likewise we will always have war, famine, sexual immorality, etc., etc., etc., etc,… until He returns for us!
And the good news is He Will Return! 
You have to learn (as I recently did) to balance the good with the bad – with the scales weighing in favor of the good. You CAN turn off the ‘nightly worldly news’ and you don’t have to stick your head in the sand to do it.
Step one:
Kill your TV.
