It is absolutely impossible for a teacher to adequately meet all of the mental health and socioemotional health needs of our students - nor should we try.  In a world and society that's  "all about me" and relative ethics, we have to focus on developing a classroom that is all about driving academic content and building relationships.  We can't allow the fires of the world to flood our classrooms.  While they certainly impact our classrooms because learning environments should reflect real life, effective teachers know that we have to focus on why we were hired in the first place.
