Did I over step with my employer?

So for 5 months my new manager everyday has told me I’m not fast enough, work isn’t good enough, and worthless. I’m fine with feedback, but I’m literally doing everything I was trained to do. So yesterday she was just going off on me and I said can you please not talk to me like that. She was like what did you say. And I said, I will greatly accept feedback, but if it’s only to try and bring me down and I’m doing my work how I have the past year without issues, please don’t talk to me like that. So she told me not to come in today but technically I still have my job. Did I over step?
