Sincere condolences Bill.
There is no more pain and suffering for her and your unbearable pain is part of the healing. Its a roller coaster that lies ahead for you and know that we are here for you as best we can be over the Internet.
As someone has already said, be sad, get angry (very angry) ask "why?", think of your times together, what you did, what you still wanted to do, smile, laugh, cry. Look at photos of her, of the two of you and remember her how she would want you to remember her.
My thoughts are with you buddy.
