Anyone got themselves into terrible things because they can't say 'No' to their parents?

My parents always got mad at me if I ever agreed to do something that went against their wishes. They yelled at me. A lot. So, I realised growing up if i just said yes to everything, I would be able to avoid the potential conflicts even if I didn't want to do that thing. Not that it worked most of the time.

Regardless, I didn't think much of it before but they are trying to get me married back home this month. I was scared to say No (I did say No but they yelled at me more and manipulated and scared me into saying yes so I said yes, I have a whole another post about that story).

Just wondering, like.....I never understood why am I so scared of saying No and then sticking by my words. I always give in and at this point, the blame is on me. Because I am harming myself too. And I just want to know the psychology behind it and how can I overcome it.
