You sit down and remind yourself of the YEARS of happiness and the thousands of good times you had. You don't let that moment of sorrow replace all of the love and pure joy that has been in your life all of the years. I don't know if you will be able to get over it easily, I know I wasn't able to. But you do something to help you along, you make something, wear something, buy something that will help you keep a little piece of them always close, always as a reminder.
My friends bought me two frames with pictures. One was a saying as the frame and the other was about 15 small pictures put together in a memory frame. Truth is you'll never 'get over' the loss, and honestly I don't think we should be able to. They are a part of the family and are a piece that keeps a lot of tension off and keep us healthy.
