Hello and welcome to the family. I can completely relate with your journey and my BPD/bi-polar daughter was in that exact scenario approximately 13 years ago (she's almost 27 now).
First off, yes, the in-house treatment programs for teens is like going to a sleepaway camp. That drove me nuts as well, and my kid would come home with all new best friends (who would eventually lead her to her next spiral as the others became suicidal). She would steal cars to drive across the state to save others, she would run away from home, the list of behaviors were endless.
My kid was also super smart, low genius IQ. In 7th grade, she scored in the top .1% nationwide in math for the standardized testing. It was the highest score ever in our state, yet she got a "D" in math that year. She deserved an "F" but they had pity on her because that's when all the in-house stuff started.
For the "this is the best place ever!!!" comments...that's only a partial truth. Your kid is learning manipulation and she'd never tell you that she doesn't want to be there. Why? Because she can't let you win! Those places are really nice though and it's necessary by law and to build rapport with the specialists.
Additionally, what's actually wrong...they don't diagnose most mental illnesses in the US for kids under 18. That's because once it's on a chart, it never goes away, and a lot of it is juvenile rebellion. Still, the longer she's in places like that, the sooner you'll get an unofficial diagnosis. So it's a game you must play.
For my BPD daughter, the pattern was that she'd get down, be institutionalized, and meet others in the same boat as her. They'd bond over commonality and develop super-deep connections, and the mirroring was also common. Once something happened to one though, the others would go into crisis mode right alongside them because they'd have to "save each other". But then they'd backstab one another and that's another round of treatment needed as they reeled from the betrayal.
The in-house facilities for teens are horrible...yet they're your best option by a longshot. The only other path is finding a local therapist your kid really connects with.
Again, I'm so sorry to hear someone else is going through what I went through...I wouldn't wish it on anyone. You have to play the game though because there's no other option.
