MAN CHILD!!!

This is  what  I call my  16  yr  old  son. NOT  a  adult  NOT  a child..... what  to  do?????? gurrrr  what  happened  to  my  sweet  little  boy  that  would  run up  and  hug  me  and  tell me  he  loves  me  forever, now  its if  Iam lucky that I get a  HI  in passing as he  walks  out the  door. I get  so  angry  at  the  moods  he goes  threw  cuz  he is  stuck in the  middle,   it  is  frustrating  for  BOTH of  us. At  this  moment  he is  trying to  show  me  he  is  grown up  by  telling  me what I  should  do and  when I explain   to  him  he  can not  do  that  ,he just  gets  mad  and wants  to  start  a  argument. I  have  called  the  school  and  asked  for  help    lol that  was a  joke  it  was like  running in to a  brick wall .  I hope  things  get  better
