I went shopping one day and found the most amazing ring at a jewelry store. It was a London Blue Topaz, something I had always wanted. I decided to buy it for myself as a celebration and a reminder. I had it sized, and picked it up on the day my divorce was final. It's a lovely ring and I treasure it to this day - a visual reminder of the beginning of my wonderful new life.
Perhaps you can do something special for yourself, too!
