You are absolutely doing the right thing. If having this girl in your home is making you miserable, it is difficult to provide great care for other children - believe me, I know! I only lasted a week though - good for you for persisting, but it is not worth dreading each and every day! Just know that you are doing the right thing for yourself, your family, the other children in your care and even the child that is not the right fit for your dayhome!
