I think it's good that she is expressing her feelings to you like that. It says a lot about the type of relationship that you have with your daughter - you are doing a really great job if she feels safe to vent to you like that.
I also think that sometimes our kids know just what to say to drive a dagger through our hearts. She's probably not happy with you because of the move and she wants you to feel bad for uprooting her like this. How do I know this? We just moved a year ago too! I have tween/teen boys. It has been an adjustment and they really miss their friends, family and routines from back home. I can't blame them - I miss home too

. But at the same time, being in our new area has held a lot of good things for us too. It's going to take time for us.
Now back to what your daughter said. If it makes you feel any better, there would probably have been angst and drama and self doubt even if you had not moved. And she would likely have been envying the "in" crowd regardless. It is part of being a teenager. The best thing we can do is try to encourage them to get involved at school and to try new things. If one thing isn't a fit maybe something else will be. Also, making home an oasis where she can listen to her music, hang with her family, have her favorite foods does help. Also - daily exercise. Bike riding, walking the dog, jogging really, really helps to take those hormones down a notch. Hang in there.
