I was the teenager from hell, stayed out all night, drew ink lines up my arms to suggest I was shooting up (too much of a wimp to actually shoot up) gave my parents a lot of cheek and challenge, flunked my O levels and competed with rest of my friendship group to be naughtiest girl in the school, nearly expelled when we inadvertently set fire to the boards at the end of the tennis courts whilst smoking behind them in hot weather (stupidity compounded by being the only ones walking away when rest of school running to see). They are not only loving parents, they were strict about boundaries too. It's just I couldn't resist bouncing against them. I am sure I hurt them and tested their patience. The only thing they may have been guilty of was naively, they didn't realise the half of what teenagers got up to in the 70s, and they didn't realise I was dyslexic, hence the problems at school. However I never lost touch with the values they had given me, however much I appeared off the rails it was mainly for show and bluster. And when I needed to I got my head down and got the results I needed for uni.
My teens have also challenged us, and my parents have very much enjoyed it being my turn. But like me they have the right fundamental values, all those values that you bring them up to have, if they are not there by 8 or so, it is too late. Scratch the surface of the rebellion and it is still the same little girl I have loved from birth. Being fully aware of the dangers out there i have been strict, no binge drinking in the parks at 14, "all my friends do it" is no argument. My DD1 is now 21 and says she appreciated our strictness, all those girls who were allowed to stay out all night and do what they wanted weren't happy.
I think OP has to disentangle the element of teenage behaviour that is sparked by hormones and developmental psychology, and that which is sparked by other factors, peer pressure, personal problems, genuine mental illness and yes in some cases but not all, a lack of boundaries on what is acceptable behaviour.
