Am I Really That Bad?

So I'm at my mom's house this weekend and we don't do much. When I'm at my dads house he forces me to go out to these things and I really don't want to do. I really don't want to get into why my mom and me started arguing but I am simply expressing my opinion when she starts yelling. She slaps my arm really hard and yells about how I am such a brat how she works her butt off for me. She then pulled my hair and yelled about how I never act this way at my dad's. After a couple of minutes of silence she says that I treat her like shit and how I never apologize. At this point  I'm practically breaking down and I really don't see the need to apologize. Reader I want to tell you something, I never really express negative emotions at my dad's house because he could hit me a lot harder then she can. I only express negative emotions at my mom's  house because you can never tell when she's about to explode. Please tell me if she took it to far or I should just stop showing negative emotions at all.
