Students we can't help

This post does not have anything to do with a response to a weekly reading.  This has to do with kids that we as teachers can't help.  I have had a student in my classroom since last April.  I had him repeat kindergarten because he did not meet standards.  He came to me from another district and came with an IEP for behavior.  He was violent at the other district . Medicine has controlled the violence, but there are other serious issues.  This child has some very lets say, challenging behaviors and nuances not normally found in 5 year olds. When he is in the room, the vibe changes and things can be very difficult.   After a long process, the district finally went through the testing process to try and find a diagnosis for this child.  He has finally been diagnosed EI, but the psychologist and I know there is something much more deeper.  He has issues that are beyond the scope of the public school system.  He is too young to label with the appropriate label.  We as a country, flow kids that have very deep emotional and psychological issues through a system not capable of supporting them.  We go through the process of teaching them, graduate them and release them to society.  This will happen to my student and I am fearful for him and others like him.  I am also fearful for myself and others that will teach him.  What have we come to in our country with helping kids who really need help?
