Trauma is everywhere, however we rarely talk about the important of awareness. The first step is to understand what trauma is and realize that it changes the brain. What I've learned is that healing also changes the brain and that's why I created the Social Emotional Alphabet which has grown into over 50 practical strategies to help educators, parents and coaches work through tough behavior. Always remember that behavior is communication. Behavior of others is not about you, rather it's communication of deeply rooted issues.
My middle school is currently in the process of implementing restorative practices for discipline vs exclusionary practices. Your last line that says "Reclaiming life takes compassion, positive adult connection, and a lot of time." could not be more true!
