I understand how you feel. Only time can help ease the pain, but I don't think we will every stop missing our parents. My Father passed on 04/14/1997 and I still miss him. 14 years after his passing, Mama passed on on 02/14 of this year. She was 80 years old, still, no matter the age, and knowing she was activily dieing the 1st three months were hard. I cryed all the time, these days I cry a bit less, but if something remainds me of Mama, I start crying.
I think the 1st year is the hardest, specially if the passing is sudden. I am from Eastern Europe. In our cultur its comment to "wail" or cry with feeling and verbale expression. My daughter felt uncomfortable with my expressions of grief, so I "wailed" when I was alone.
It has been five months of Mama's passing, but I shall miss her as long as I live. My world is not the same anymore. There is something so final loosing a mother. May the memories you have give you the comfort you need to face each day.
Accept my deepest sympathy and just take it one day at a time. I think crying is good and healing, just make sure you drink plenty of fluids if you cry alot.
I wish you peace.
PS. My Aviator pisture is of my Mama
