Linda, if I can tell you one thing, find a grief support counseling group. A grief counselor is good but when you sit down with women and men who know your pain it makes all the difference in the world. It is the only way I have held on. I was terrified of doing that myself but you will not believe how much it helps to be with others who understand what this feels like. Honestly, it probably saved my life.
I'm so sorry this happened to you and I understand exactly where you are coming from, I feel so lost. It hurts so much. I have no concept of the word "normal". Nothing in my world will ever be "normal" again, whatever "normal" means. Thank you for sharing with me, know that I understand and my heart goes out to you.
Be Well,
Amy
