Try not to get worked up. You can't cure it, you didn't cause it, and you can't control it. Nobody is trying to trick you or lie to you. The media has "slow periods" and at this point there's not much else to talk about, plus it gets ratings. AIDS is still a much bigger epidemic but Ebola is the hot new thing. Remember the NFL and Ray Rice and Adrian Peterson? That was the same style of reporting. Now it's Ebola. Next it will be something else. That's all. Watching cable news during the daytime hours does feature "repeating" because most people are working and their viewers are more or less cycling out every 10 minutes or so.
Focus on keeping yourself happy and sober. What can you do for yourself today?
