No of course not. I was going to say , share it with him. Because kids tend not listen to there parents. It stops you from doing so many things and socialising. And this will be a big part in his anxiety. Or could of even caused it. But I don’t know the times of when his anxiety started and his using.
But if I was his age again.id cut my friends off – the using friends, and I would go to college and learn a plumbing course or something. Or get my gcses then go from there. He still has the time to do all this and have a great future. Good luck.
