Today my 17 year old son threatened me (again). He made a fist and pulled it back and I instinctively raised my fists to counter the attack. He did not follow through.I told him if he hit me he would seriously regret it. He used to be such a good kid but the last 3-4 years have been a trial. I am wondering what I should have done. I have filed mental hygiene petitions on him a couple of times. Sometimes I wonder if I am safe around him.
