How Can I Get My Foster Daughter Back.

I don't usually post because I am not one to post personal stuff online, but I really need help. My Husband and I took in a 7-year-old girl a couple of years ago. She had been kicked out of several foster homes already, and they were considering a children's home for her before we took her in. There were a few behavioral issues, and she had a medical issue that had her still using a pull-up. She had lost the only Dad she knew a few years prior, so of course, there was trauma there, but we were willing to take it on and work through it with her. It was hard, but we were willing to stick it out. She was already on medication when we took her in, and when she got upset, she could get rather destructive. She even tried to run off a few times. She was getting better with us, and we discovered what a sweet, loving girl she was. Foster care took her and put her in a facility for a while to help her with her anger issues, and it seemed to help, as when we got her back, she was a lot better at handling her emotions. The only problem we really had was that she was refusing to go to school; she is nine years old at this point. We were still working on adjusting her meds, and her psychaitrist told us to take her off one med while she was transitioning, and we did. This did not work out well, as it really exacerbated her behavioral issues. When we resorted to her original medication, she got a lot better. Because she wouldn't go to school, her social worker took her and sent her 8 hours away to a children's home. We understand that she had to go so that she could get some schooling, but now her social worker is saying that it isn't in her best interest to go back with us, the family that loves her and wants to adopt her. They don't think we are a good fit because we had a few difficult times with her. Sorry if I am being vague with a few things, I just don't want to give away anything really identifiable. My question is, do we have any legal recourse to get her back? We love her, and I know she wants to come home. We are her family. Any advice would be appreciated.
