This recently came up again for me. I rebelled at about the age of 13 after my parents did not want to respond to my emotional problems. Even now my mom talks about how I turned into a monster at that age and I'm not almost 49 years old. My brother is the golden child although he has narcissistic traits but is charismatic and hasn't had the problems I've had. I still feel like the outsider and periodically I clash with my parents and am criticized for being different. It hurts.
