oh boy oh boy, that is a TOUGH question.
my son went to live with grandparents. Any expectation i made of him (ok, you need to clean up that room. get out of bed, you'll be late for school again) was met with
WHY, YOU GONNA LOCK ME IN TEEN JAIL AGAIN? He was in "teen jail" for 3 weeks.
so, he had to go, i couldn't continue, b/c of my guilt to let him do as he damn well pleased. we needed time away, and i love and trusted where was going to get that time away.
firstly, get him help, my son had post traumatic stress, and his behavior was wild, strange and unpredictable b/c of it. Way worse than when he went there. outlandish and absurd, to put it lightly. where was son??? the peson i left there was not the one that came home!
Secondly, (give therapy time to work), its been over a year for me now, and depending on how long your son's stay was and much convincing by you that you had good intentions, and his best interest inmind, how the program had manipulated you, and how WRONG they are), he may come around. When my son told me some of the things they had told him while there, such as, "you are so bad even when you finish the program, your mom probably wont come and get you). I had a lot of undoing to do. They told him he was damaged goods and a "bastard" b/c he doesn't really know his dad. More undoing.
EVENTUALLY
My son, who failed the 9th grade, twice, and refused to go to school, is now an honor roll student. He told me last night that the one (and only) positive thing he learned at Wasp was to appreciate all he has and how much we all love him.
This helped for me: I got really quiet and serious one night, took my son by the hand, and looked him in the eyes and told him the truth. I said you are the most important person in the world to me and i love you more than anything. you are more important to me than my job, social relationships, material possessions. You are #1. When there's a problem, i need to know and we need to work it out calmly.
go back to first - get professional help, give it time, medication, make him your priority, even if you have to let him go into the hands of a family member you trust (grandparents, aunt, uncle) if needed.
