I lost my sister on 3/20/09, our mother's Birthday. Your feelings of anger and depression are normal. Being in denial, I believe, is also completely normal. For the first 4 months after my sister was murdered, I still thought she was going to call me. I still listen to some of her saved voice mail messages so that I can hear her voice. Gail left behind a 15 year old son and a 9 year old stepdaughter. I've attempted Group Grief Counseling sessions, but have not gone back after one meeting. People try to tell you that things will get better with time. Unfortunately, I don't feel that way and it seems for me, that things are getting worse. Feel free to comment back to me and I will be glad to respond. Losing a sibling is so hard, but I feel so badly for my parents and can't imagine how they are coping with losing one of their children!
