What age did you realize your narcissistic parent/s were hypocrites, and when did you start rebelling because of that?

I've kind of always known, but I spent years telling myself that they were just trying their best and were actually trying to help. I was 19 when I realized they actually were narcissists and doing more harm than good. I never rebelled; I just moved out as fast as possible, spend as little time with them as possible, and know that even though I am "welcome" to move back in, I will lose all of the sanity I finally regained since leaving.
