Was I wrong?

For thanksgiving my aunt asked that we all bring a homemade dish, kind of like a potluck, so that one person wasn’t responsible for everything like in the past which caused tension and stress. I’m a college student and currently going through final exams right now, plus several different projects and work 40 hours a week. I originally planned on making 2 homemade pies but because of my busy schedule I truly wasn’t able to fit it in, so instead I brought store bought pies thinking it wouldn’t be a big deal. However when I got to my aunt’s house she made a huge scene about it, saying I didn’t put any effort in at all and that it shows. She basically said I shouldn’t eat everyone else’s food if I don’t want to contribute my share. I told her this holiday is more about being with loved ones than keeping score of who brought what and told her I was extremely busy this week with college and work. She told me to suck it up because her daughter (my cousin) was able to make homemade green bean casserole even though she has a toddler. I ended up leaving my aunt’s house in tears before my mom and dad even got there. My mom called me asking where I was and I told her what my aunt said to me and that I didn’t feel comfortable coming back and it caused a huge argument between my mom and aunt. Was I wrong?
