Life goes on. The period around my divorce was the low point of my life, and no one's advice made it any less so.
I discovered Tae Kwon Do at that low point, and the intense focus and drenching workouts, washed away a huge amount of the pain and anger. I also rediscovered diving, and found a peace I had almost forgotten existed.
I took the Nietzsche quote "That which does not kill us makes us stronger.", and the line "success is the best form of revenge", to heart, and decided to focus on my own growth. Today, I can sit quietly with my X and discuss our children, and feel none of the anger and pain I once was filled with, and even last evening I sat and had a couple of beers with her newest fiance, and felt sorry for him.
It took time to find this peace, but looking back on what was, and now is, I am better off for having moved on with my life. Occupy yourself with improving the person you are,
for yourself, and in time the pain decreases. Make friends, stay busy, find things to do that bring you peace, even if for just a minute or two at a time, at first. All these help to move you down the road, and lessen the pain and anger.
