Glad you decided not to go. Think only happy funny things about your mom. Remember as she was and that will help you cope. Also whatever emotion you feel is the right one. Scream, shout, cry ,hit a pillow if it makes it easier for you. I only wish when my husband died aged 47 I was 45 feeling not just of loss and sorrow , but anger and rage where all normal emotions to grief. Had to learn that myself. It's been 17 years if what I have learnt helps one person then something good came out of an awful time. Grief for my husband has never died. But coping gets easier as the years go by. But the grief deepens as he has missed so much. I still love him as much to day as I ever did. And that makes me happy.
So be happy for the mom you remember and love.
Anger management!!! Help needed.
