Am I a horrible person for letting this continue to bother me?

So tonight my mom came home and the table wasn't set for dinner. My sister and I had been talking and we simply forgot, but as soon as she came home we immediately went to do it. This still did not make my mom happy. She called me useless and said she wants me to quit going to school and get a full time job . I work part time and help out when asked to, including assisting my parents with dropping my little siblings off at practices and stuff. Of course she went back to normal after dinner, but without an apology. Is it bad of me to still be hurt, even though she went back to normal?
