Antigen has the right idea. I don't know if biking cross country is your daughters thing, but I would definately recommend that you take some time off, go on a trip together, and get to know your daughter again. It sounds like you two have a lot to talk about. Leave your home environment and your problems behind, go somewhere new for an extended period of time, and share an adventure together. She may or may not resist the idea at first, so be patient. Being at cedu is a traumatic experience, listen to what she has to say. Tell her where you stand.
No matter what kind of attitude she may cop at first, she is your daughter, and deep down inside she loves you just as much as you love her. Show her that you want to make things right. It might not be easy, but I'm sure the two of you can work out your problems together. Best of luck to you. You made the right choice.
