Dear worried girl,
Stop thinking about what can happen and enjoy today with your Mom and other family . Everybody dies from something some day but when ,only God knows. I do know how you feel,since I lost both parents, grandparents and my son who was only 22 from another horrible disease. When I lost my son I thought I couldn't go on and I really didn't want to, but here I am. I can tell you it gets easier, how long it will take I can't answer that. I talk alot about my son and I feel he is with me and he is at peace.
Please stop thinking about tomorrow and live and love for today,Nobody knows what tomorrow brings.
Take care my thoughts and prayers are with you and your family,
