Is it wrong for me to feel hurt?

It was supposed to be a relaxing dinner with my mom, but I made a small mistake and my mom yelled at me and called me a retard. I couldn’t hold my tears in and locked myself in the washroom. She started yelling and banging on the door. After shutting in some more, I told her about the effects and offensiveness of the word and how shocked I was. She just said yea you’re a retard what’s wrong with that I don’t get why you’re crying. She proceeds on talking about her own stress in life. I understand her stress of going through financial difficulties during the pandemic but is that a valid reason for me not to feel hurt?
