If she had such a wonderful experience on a wilderness camp, then take one yourself together with your child.
The key element (and in many cases the only element) in therapeutic boarding schools and wilderness programs is
isolation.
Isolation from all influences in the society - good AND bad:
Isolation from good things like friends, family and school.
But of course also bad things like alcohol, drugs, sex etc.
Some of the problems of understanding a teenager today is that your experience of being a teenager is some 20-40 years old.
I grew in the 1970's without internet and where drug users where corpselooking teenagers with a needle in their arms. See:
Christiane F. They do not look like that today. In every High School class in Denmark there are 2 or 3 drugusers and most of them manage to be occasionally users until they are about 25 , where most of them either quit or get killed. (It is so rare that a teenager is loosing he or her life due to druguse that it is frontpage news in all newspapers nationwide).
So if she had a good stay, it would not hurt her to go there a second time, but this time you should got with her a stay at her side all time, while they give you therapy. Perhaps then you will bond with her in a way you would ever hope to achieve.
Perhaps then you also would learn what you really put her through and she otherwise would never tell you before she turns 18 out of pure fear of being shipped off again.
You should try
Aspen Family Camp, but I have to warn you. When they used it in Brat Camp Uk the reality of wilderness therapy was so harsh on the parents, that a family did quit. That is a privilege a parent has. Such rights do children not have.
So try to learn to know your child. Let the next step be emotional growth for your boths (or in your case. An update to teenage life after the millennium).
