The others are correct, the situation is still new to her and she needs time to adjust. In the meantime what you can do to help ease her being left alone is to give her a special treat that she gets only for the times when she will be by herself. The treat could be anything that she really likes such as a kong toy stuffed with her favorite food. This can help her associate being alone as a good thing.
