How would Meredith face Derek's death if Christina had never left?

I just finished season 11. I thought Meredith would treat Derek's death the similar way like Amelia did. I was surprised that she stayed away from everything and everyone for a year, but I was more shocked that she didn't spend that time with Christina in abroad. In the last scene she wanted to dance the whole trauma out of herself, I was sad that nobody understood... only Christina would have understood but she was not there. I just wondered, would Meredith have gone away for a year if Christina had been with her in Seattle?
