Absolutely. The way we were raised has a direct impact on our mental health as adults. As a kid you register everything. As a kid you also think your parents are the best people in the world. So being belittled by them means a lot...and that damage may take a lot of effort to repair.

I find the word 'hate' particularly harsh. I do not hate my parents, but I do not have any sort of sentimental connection with them...which is sad! I think aiming to repair these relationships is essential in order to grow as a human being and in order to be at peace with oneself.
