My mother died 3 years ago and I cried every night for a long time (3-4 minths). I didn't cry for her, because she was in heaven, I cried because I missed having her in my life. I imagine it will be the same for you.
Spend as much time with your Dad this next year. He will need your support. After many years, it's hard for a man to have the empty house at night. It is important to share with him your memories. It is important to allow him to talk about her, even though it it painful for you. I share your grief, but you will see her in heaven. Live the life she would have wanted you to live. Make her proud.
Angel, thank you for your very good advice. My own mother died February 7, 2004, after battling many illness including liver cancer. What you have said is correct. While I don’t cry every day, there is not a day that goes by that I don’t think of her. Poppyseed, eventually, your grief will subside and will be replaced by a warm glow as the memories and acceptance take its place. It will happen although it takes time and things will by cyclical.
Angel, I am afraid that you and several people here were confused by my posting this thread in the manner I did. Kayak was my good friend and supporter. Poppyseed is her daughter. I understood the misconception and I hope Poppy realizes that condolences expressed to me are really meant for her. (((Poppyseed)))
