Wish I'd read this comment before replying right away. Neural plasticity studies/positive psychology have shown that you can actually train your brain to start looking for positives instead of focusing on the negatives. If for example you start writing down 3 positive things a day that happened after a few weeks your brain will be on the look out during the day for more positive things. And it's not that the percentage of positive things increases, but your awareness of them does as at the same point the focus on the negatives goes down.
As someone that started doing this about a year ago, it's worked for me. Bad things still happen but I deal with it and move on and I'm less apt to dwell on it.
