J.N.
I am so sorry for your family's loss. I lost my sister in 2000 just 3 days after she turned 16. A drunk driver killed her as she drove home from school. While my children never had the chance to meet her they know all about their special Aunt who looks out for them and watches over them. Some of the things we have done is we celebrate Kristen's birthday, we started a foundation to honor all of the dreams she had & give college scholorships to those students who want to study in the same field as she did. At Christmas she still has her stocking hung with all of ours and we made a special tree just for her....it is an Angel tree.
I can tell you it took about 3 years before we all were over the anger of Kristen's death. Please don't be afraid to see someone to deal with the anger and sadness that comes from such a great loss.
My thoughts and prayers are with you and your family. You will make it through, it will just take time.
J.
