I agree the news can get pretty depressing. It's a bit of a relief when the local news shows thirty cats and kittens seeking new homes instead of all the violence.
Remember the old saying "Peace has never been achieved through War", it's true.
When I don't want to listen to the news, I come and visit my favourite forums. Sometimes I'll re-read about the battle within of a once grumpy old man who said, "bah" to Christmas and later after being visited by three ghosts (and of course the Ghost of Jacob Marley) became a kind and peaceful Ebenezer.
If you are feeling down - Think Christmas! It does the body good!
