There are bound to be days like this Lisa,just before Xmas I had the radio on and they played a carol my mum learned at home for her infant classes nativity,I was astounded to find myself crying it is 11 years since she died.Once you start feeling down you start feeling down on yourself and questioning your decisions but I know you did what you felt was best for Brad and it seems he was quite calm in the car when he mentioned it.
Your grandad would be so proud of you and everything you have achieved.
