Well till she is ready, you really can't force her to face reality! It takes time to heal, and till some people hit bottom, they won't get up off the ground. When she's had enough of things the way they are, she will!
I think you have to wait until she is ready to share her feelings. In the meantime, just try to be there for her. Comfort her and make sure that she doesn't fall too deep into depression that she hurts herself. Just let her know that you are always there for her.
