Abuse

I don't know what to do

So I'm dog sitting with my mom for my aunt and we're leaving soon. About ten minutes ago we were walking her dogs so they would go to the bathroom before we left. My mom asked me if the dog I was walking peed or pooped and shook my head and shrugged. She yelled about how I never pay attention to anything and that I'm lazy. She slapped my arm and I started crying. She asked what happened to her well behaved child then I asked what happened to my kind mother who wasn't abusive. She told me me to sit on the couch inside, she yelled about how that I know nothing about being abused and how I needed to be beat to be a good kid. I was practically having a mental breakdown at that point. She left me to calm down and after 20 minutes we left my aunt's house. Please tell me if who think I was wrong to keep calling her abusive or you think that she is abusive.
