Dilemma, it's the not being able to share it with the people it should have matter to that is the worst.
My DS2's and DD's birthdays are so hard, I am no longer with their Father, Mom has died DS1 was only a child, when they came and went in this life.
It seems that only I remember them.
Take care and grieve for you child on her birthday tomorrow is another day, when we get on with our lives, with a small corner of our hearts torn.
