Absolutely right.  
One of the Head Start curriculum domains (to which reading materials are correlated) mandates that children be taught "differences" and there are book collections that address all sorts of physical differences and disabilities.  I've had requests for PreK books on dealing with emotionally stressful situations.   

However, when you look at grades 1-12, the Florida State Standards for Health Education focus on physical health:  communication, making healthy and safe decisions, hygiene,  and health practices and behaviors.   There is mention of some  conflict resolution, but I only see one benchmark for each grade that includes the words "mental / emotional" within a larger topic.

Ways to effect a change might include:
a)  send some "warning sign" literature home to parents, with indications on what to do if they're concerned
b)  assure that all juvenile detention facilities have a literacy component which takes aim at creating a desire to read, (with age-appropriate and reading-level-appropriate high-interest supplemental materials) and then we  can segway the kids who "take" to reading into more high-interest materials and writing exercises that start the dialogue. 
c)  start a social media campaign aimed at teens, teaching  them the warning signs of mental illness . . . get them involved in the process of watching out for potential offenders, knowing what to look for, and who to tell when they see something that reads tilt.    Teens relate to real-world stories, particularly dramatic ones.   I think creating blogs by imaginary teens with mental problems could be one way to get this info shared quickly.   Think bottom-up instead of top-down.   Kids listen to each other a lot more effectively than they listen to authority, in many cases.   This might hold even more true in the demographics which present more of the problems. 

And this ties in with my theory that we must do whatever we can to educate at-risk teens on what the library has to offer them.   (Part of my recommendation for Juvenile Detention facilities, as well as Reentry facilities).  The library is often where at-risk teens go to use the computer, share information, and socialize.   

It could behoove the Collins Center and other orgs interested in justice reform to have a literacy resources consultant on board, and one who is social media-savvy would be a real plus.    Books, ebooks and the web are windows to understanding and change, and there are lots of ways to create the desire to look through the window.
