My lovely daughter is having a baby, due later this year. The whole family and friends are estatic, her dad is over the moon at the thought of being a grandad. I keep telling myself that I'm happy and appear so to everyone (except my husband who knows me too well). I know I should be happy but deep, deep down I don't know what I'm feeling, sort of numb I suppose. I have fantastic relationship with my daughter, she will be 25 when the baby is born, she's in a good relationship and her partner's lovely so why am I feeling like this?
