What's your worst nightmare????

My worst nightmare would be to loose my husband, 1 of my children or grandchildren. What could be worse than loosing someone you love. I have already lost both parents and 2 brothers so I know what that feels like but to loose someone you are with 24 hrs a day or a child that you have given birth to has to be the most painful thing a person could go through. A grandchild would be horrifying, because you have to deal with your lost, plus watching your child going through it to. I don't know if I could handle it. WOW That question stired fear in me....
