I've managed to avoid residential treatment, but mostly just because I'm a single mum and have to be around to look after my kiddies and stuff
but my best friend's done residential twice and both times it was really good, the second lot better than the first but still both effective containing helpful.
Oh yes, and she REALLY didn't want to go either time so it's not like she was set up for it to work.
But I also totally agree about making sure it's not the boot camp thing, she was in a hospital ward once where you had to earn points just to have basics and the attitude was about control not compassion.
Good Luck, I really hope your parents don't want you gone but rather want you to get the help they feel unable to give you
