Im sorry for your distress, but a baby will be born when it is born. Im sorry that I cant fix it for you, but no one can. Since you cant change the date, and you cannot really
then you need to find the right way to turn it around for yourself.
Im sure your father would want you to take joy in the occasion no matter what, any loving parent would. I know it can be hard, and the older you get, and the more people in your life that you lose, you realize all you can do is take joy in the new lives around you.
I really dont want to preach or pontificate, that can just rub a person raw, but you have to find the answer to it all in your own mind and heart. I really wish I could help more, and I really do sympathize. ((hugs))
