The thought is tough but the reality of your leaving us is far more bitter.  
My beloved daughter, the most feared thing has happened,  I, your father must eulogize you instead of writing a poem in your autograph book.  
Those were days of joy and happiness and love in a joint concerted effort to deal with the problems as a result of your illness.  I am happy to put this in writing that you my daughter with all the pain and suffering that you endured learn the important and positive that God gave the world. My dear daughter, the more that time passes the more I’m aware how great the loss is. I recall you going to school, and participating in family celebrations. I see your smile when you would set the table before the many guests who came to our home for parties, holidays, the Sabbath or just an ordinary day.  I remember your joy when we celebrated the holidays with the extended family. 
Thank you that you were with us and gave us the privilege to be with you for 16 years. 

Your Loving Father.
