Calling your son a "loser" because he has bad behavior and unwise choices is not going to help anything. I am very unfamiliar with parenting a teenager and I'm sorry you have having a rough time. I was a teen recently and I do have to point out that the teenage years are very hard mentally and he could have depression. I was very depressed in high school and, quite frankly, there's no reason NOT to do those things when you are depressed. I'd find something he enjoys doing and start reconciling your relationship... Good Luck.

Been there done that !!! My son had a rough couple of years, and was kicked out of school. I grounded him to the point that he was not allowed to so much as have a phone call unless I was standing there. It took almost a year but he is now a joy to be around most of the time. I was grateful that he got into trouble with the police, as it showed him that there were very real consequences to his actions.
