Hi! My son (17 year old ) has changed a lot since last 3 months. He is becoming more arrogant, more indifferent. He gets violent for very silly reasons. He gets back home late at night and I recently came to know that his new set of friends are a set of drug addicts and drug dealers. I'm scared! I do not know how to handle this situation. I'm a single mother and there is no one but only a close friend of mine with whom I can share my problem with. She said that I should sent him to an addiction rehab center. I'm ok to send him but I do not know how to tell him about this. He will never agree to this. How will I make him go?
