I know how you feel sis. My memories of Christmas as a kid was the joy I had with moms family, My grandparents and my aunt, It was such a joyous time (My dads family was so huge, we prety much was side notes, but I loved that too)
My Mom, Grandma and grandpa, and Aunt have all gone to be with the lord. This is about the 5th year alone, and it is still rough..
My dad is starting to lose his mind, and my brother and sister, well lets just say it is not a good thing.. So I have no family either.. Except my wife, her two kids and their families, and my oldest I had christmas with my youngest last sunday, but it is still not the same, because will still be with out family most of Christmas Day.
But I think of where I was when in th emilitary when I had nothing, and all those who have no family left. And I have to just praise God I have what I have..
so I will say a special prayer for you, because I know what you are feeling..
