My son has is 18 now but has been experimenting with drugs now for a few years he has terrible mood swings and is always causing a big scene drawing attention to his self I’m so concerned about his behaviour as at times it’s appalling and scary he seems to be taking percription tablets xnax he seems to dislike everyone and most of his friends from school no longer bother with him I live a very settled life but he is constantly on the move every time things get a bit tough… so confused
