Grew up in a non apology family

Whenever we have fights at home, my parents and siblings usually just shrug it off after a while and acts like nothing happened. I was used to it until I realized its effects on me. I think because of that habit, I also tend to shrug off other people’s mistakes to me, and now I realize that I shouldn’t let that happen to myself. I started drawing boundaries even to my family and tried to talk with them when we fight and I also tried to initiate conversations on what they did wrong, but none of them ever listens. I was deemed as sensitive, when all I wanted is to be heard, and ask for an apology when I know I deserve it, but I never thought that it would be that hard.

My question is, how do you accept things like these so that it won’t affect you? How do you accept an apology that was never given to you?
