What do I do?

So my mom chose to start a fight with me the day before mothers day, now i don’t know what to do.. here’s what happened, I had a car that was mine and in my name, I recently got something else bigger because we just had our fourth baby and needed more room. A few days after getting this vehicle I sold my other one, I just no longer need it. It’s been a few days until I sold it and my mom called me this morning and asked me something about the car and I told her I didn’t have it anymore when she asked me why I told her I sold it. She started going off saying how stupid that was and how ignorant I am and how I let my husband make all my decisions blah blah blah and it wasn’t his decision it was mine the car was in my name it was entirely my choice he told me to do whatever I wanted with the car. Which she blames him for everything, she started throwing up in my face that I have 4 kids (which so does she) just talking crazy for absolutely no reason, and this is how it is all the time. Everything we do is stupid In her eyes if it’s not something she thinks we need to do. She complains about literally everything and always Throws the fact That I have kids in my face. She has made me so mad that I don’t even want to go over there tomorrow whether it’s Mother’s Day or not. Just the fact that she calls me ignorant and constantly throws up my kids makes me just not even wanna talk to her anymore. But then again if I don’t go over there tomorrow regardless of how she talks to me then she will throw up in my face that I didn’t spend Mother’s Day with her. I don’t think it’s fair that she thinks she can talk to me however she wants and still expects me to be all nice and happy. What do I do ?
