Listener question: how can I stop my daughter suffering?

Listener question: You may recall our conversation regarding my dilemma about moving. In brief: my partner had asked me to marry him a few months ago and so a move was on the cards and my daughter was very unhappy about this. 

An update on that:  last week we moved and my daughter started her new school. Sadly she hates it. She has cried and cried and cried (as have I) the entire week. We've barely slept or eaten.  Myself and my partner have been into school and had extensive meetings and the school have put a robust system of support in place for her. My partner has been brilliant with her and of course she's getting a lot of support from me. So from that respect she is not alone. 

None of that changes the fact that she hates it. She says no-one speaks to her apart from one girl (but she doesn't see this girl all of the time because they are in different lessons). So she is largely alone during the days.  I don't think there is anything wrong with the school and I don't think the kids are being deliberately mean, I think she is just feeling so vulnerable, out of her depth, misplaced, scared, insecure, lost, shy, awkward etc. that it's so hard for her to connect with anyone- and of course the more she feels alone the less she feels she can join in and the worse it is- so it's a vicious cycle. 

She says she's living a nightmare and it's killing me witnessing it.

I'm considering moving back because I can't stand to see her suffer like this but there is a part of me that knows with love and support that I shouldn't run away from the suffering, and that neither should I be taking it away from her necessarily.  My partner is not in favour of us or her (there is an option for her to live with her relative) moving back. He feels we should work through this with her and help her get to the other side. I see that point, but I am finding it very hard to see her suffer and I want to make things ok for her again.

I feel so lost with this. Is there anything you can see that might be helpful?
