Why??????

Why do I always have to focus on the doom and gloom of my life. My daughters wedding was wonderful , she looked beautiful,and she was very happy and the sun kindof came out after days of rain and all I could focus on was my pain in the a** ex being there and ruining my day. Sometimes I want to just smack myself. I've always been one to dwell on the bad stuff. Since Bruces death I am trying to change that  and think more positive and not sweat the small stuff. He just gets my goat.
