Hello danielleclint, as other have already said, it's not your fault but your concern is a sign of caring. It sounds like he needs support, he needs to be told everything will be ok, maybe some activities as a family to keep his mind in a positive place.

When I was in the 7th grade, I was arrested at my school for having a pistol and ammunition. I was banned from school, treated like a freak, even my family just gave me this silence, it was so quiet, even after the charges were dropped and I was home, it was like I was the mistake no one could speak of or at least they didn't want to , eventually they started talking to me and asked me why. My intentions where not malicious, just poor judgment.

Is your brother interested in martial arts? I think martial arts helped me a lot growing up, for instance, I never got into a fight to this day, not even once. Martial arts could give him confidence and discipline and teach him some important life lessons while also teaching him how to stay out of trouble and to defend himself if he ever needed. Before my injury, martial arts was a big part of my life, now the physical aspects I so enjoyed are only a memory, but at least I still have the mental lessons.
