Sunny,
So sorry for your loss.
I lost my own Dad just over twelve months ago and know how numb, angry and desperately sad you and Jennifer must be feeling at the moment.
It sounds like a platitude at the moment I am sure, but know that he is still with you and celebrate the times you did have together. I like to think of it as our loved ones popping into another room and one day, when it is time we will be able to enter and be together in love, never to be parted again.
My thoughts are with you both
Tony
