A wayward son

I guess sometimes no-matter what we teach our children, they are going to do things that we have not taught them and they are going to hurt us. I find this hard to deal with.
I am sure most parents of teens feel the same way.
 (Well i think other mom,s and dad,s would feel this way)
I know i have taught my children to he honest and to work hard to make good things happen for themselves and others, and yet one of my children must have forgotten the things I have been teaching him for the last 16 years.
Honor, Loyalty, Respect and pride in your work.
Nothing like having the school call and tell you "Hey your son was caught with two pipes on him in class."
He did not come up dirty for narcotics, only THC.
ARE YOU CRAZY???? ONLY THC!!!!!!

Mind and body I went numb and my guts started to spin, wild and out of control.

I am sure it was my mind SCREAMING AT ME,

"what is going on? How can a kid that is getting all A's and B's be doing things this STUPID??????"

WHAT KIND OF THINGS IS THE WORLD SHOWING MY SON??

It seems to me these things have gone far from him and he is walking a path I did not show him. His choices have him high and suspended from school.
 His ideas and thoughts are misguided and misleading him.
 I cannot fix this in my child. He believes he is old enough to make these choices and that he alone is the one to take the natural consequences for these actions or lack there of.
 What my son does not understand or is not looking at is that these things he is doing to mess-up his life are bleeding out on his sisters and him mom.
He does not show even the tiniest glimmer of remorse or shame for his actions. It feels and looks as if he could care-less if his mom is always worried, or that his sisters cry for him all of the time.
It seems to me that this young-man is walking into the mouth of hell and he thinks there is a picnic there just for him!
There are truly not enough words to fully express what I feel for my child right now.
 I at some moments want to stand on his neck and dance about just to get his attention!
Other times I want to hold him like I did when he was little and tell him everything will be okay, that things are getting better.
But; I know nothing I do, short of locking him away from the world, to protect him there is nothing much I can do.
 I pray for him, I pray over him. I see his eyes and he looks so hollow and without hope.
 HOW HAS THIS HAPPENED???? I ask myself this every day.
 I look at myself and wonder how I have failed this child so much, so greatly!!!
Always trying to remind myself "I did not cause him to make his choices".
The strain this child's actions are taking on the home are shredding us all.
 I fear that the man of our home is ready to walk away because of this child's actions and this is a sickness that is growing.
There are no more conversations about camping and doing things together, only of "WHAT ARE YOU GOING TO DO ABOUT HIM, WHAT ARE YOU GOING TO DO TO PUNISH HIM".
I am broken from the discord in my home.
 I have to hide my tears from everyone so as not to cause more strife.
My actions have become so obsessive and the compulsions to clean and fix and move things around are weighing on me.
