You might want to take a look at Mind Matters because it is written for young people as well as adults and does explain ACES and toxic stress. There is a great lesson called "Compassion for the Highjacked Brain."
The rest of the program helps people learn skills and practices to self-soothe and build resilience.
Happy to send you a 15 day free review copy.
We also have a free website for teens, Me & My Emotions, which conveys the content of Mind Matters. It was written by college students for teens so it's very fun.
