I feel a little lost

Before I went to VA Emma was very mouthy and emotional. Since I have been back the mouthy thing isn't as bad, but the emotions are on a all time high. She also seems to be very angry. I am not sure how to deal with it. I know she is upset by me leaving and all, but it has to be more than that. I mean it is out of control. I feel like I have a teenager. I guess I am putting this out there because I need prayer for wisdom, patience, and strength. Also that I won't take things that she says personally, as she can be very mean with her words. If anyone has words of wisdom that would be great other wise please just pray. Thanks.
