I found the following article helpful in putting things in perspective. It suggests a tough but tender approach.
www.focusonthefamily.com/parenting/holding-tight-when-your-teen-rebels/.
It’s not prescriptive in detail, but I found by coincidence it followed some of my own recent approaches. Tough/tender. Good cop/bad cop. I’m not making any claims of success, as we all know what seems fine on Tuesday can feel like a nightmare by Saturday. But some of the approaches I thought might be helpful.
