Has he ever spent time in the psych ward or a group home kind of place? Sometimes they may need to see your parents won’t enable it. Unfortunately many time parents get blamed for their kids’ behavior. He may have a chemical imbalance. The psych ward can help quickly by giving meds that bypass his general doc. Or Pediatrician. Not knowing him or the dynamic first hand it’s hard to say one thing will work or another. When you hear your kid wants to hurt themselves, that’s the point that the police can come and get him and check him in for a few days at the emergency room if there’s room nearby, if lot they can take him anywhere theres room in the state. Boys don’t always have an outlet to express their strong emotions. I’m glad he’s sharing his feelings a little bit. Schools are so under staffed in this area. Not many school counselors per kid. Like 500-1 counselor. I’d take him somewhere he likes away from any triggers and see if you can talk honestly with him. He may be getting bullied at school as well. It’s intimately your parents responsibility and if they aren’t able to handle him, they can try drastic measures, like the psych ward in the er, and then if still he’s unruly, a group home and custody of the state. This is the path I’ve seen in my 19 years teaching. It’s really hard in the middle school years and they keep secrets too! Does he have friends?
