I'm sorry for going through this. I'm sure that it's difficult and I pray that you'll get through this. There are boys boarding school available and I'm sure, that will cater to your need. I don't think all are indicated only for the troubled and teens with chemical and behavioral problems. They are there to support and help the kids grow into successful individuals. They mostly consist of a small class and a lot of extracurricular activities to relieve the stress. Hopefully you'll find the school that is right for your son. Good luck.
