"My wife of 41 years died...Is it wrong for me to pray to die too?

In this episode, Dr. Betters answers the question, "I lost my wife of 41 years this year on February 19th. My life is so empty. I love God even though I don't understand why she had to die from stage 4 colon cancer. I was mad at God for taking her, but I have asked Him for forgiveness and thanked Him for giving us 41 years of a perfect marriage. My question is: Is it wrong for me to ask Him to bring me home now also?"
