Perhaps I'm just too sensitive to the suffering and plight of others, or am too idealistic about what the world should be like, or simply read too much awful news and need to stop, as 3rdgen recommends (thank you 3rdgen)!
One has to remember the news media is highly paid to draw an audience who will view their sponsors expensive advertizing . No one would tune in if there wasn't anything dramatic to report and they are highly trained experts at wringing every bit of drama out of any given situation. They have us programmed to beleive that no matter how upsetting it is to us, we will somehow be ignorant or uninformed if we don't listen to what they have to say every hour on the hour. The "reptillian" part of our brain wired for our own survival, finds that idea easy to believe and we are sucked in. I have been involved with events or happenings that ended up on the news and the way they presented it compared to what really happened is night and day. They overdramatize, distort and outright lie on a regular basis.
If you are feeling down, or depressed you need to stop watching the news. For your own well being, go on a news fast. When you are depressed or in a low mood, the negativity they purvey is amplified and the brain is flooded with even more negative thought producing chemicals. The world will go on without you having to know about every single horrific thing that happens. Most things go reasonably well for most people most of the time. The news media purposely hunt down and dwell on the ones having difficulties. Basing ones outlook on life on what one sees in the media is like peeking into the window of a classroom and staring only at the one or two kids making trouble and at the peeling paint on the wall, ignoring the the kids who are listening and learning, then concluding that schools are places of utter chaos. Yes, there are reasons to be concerned but it isn't so far gone that one's only hope is to burn the whole school down.
