Pls 🙏 I need help in judging this matter

Ok so this one time, we where at her shop. I asked her how much she wanted to sell the tap for a customer and she said 4500. So I wrote down 4500and that is what the man paid. Later on, she started shouting at me that she told me 5500 not 4500 and I was trying to explain to her that she was on call so she might not have know when she said it but she insisted that she was right and she even insulted me. I had 1000, so I gave it to her and told her that since she's upset I want to pay for my mistake, but that got her even more upset and she continued insulting me and even said the money was like an insult to her. I felt bad so I cried a lot, then she proceeded to make me feel even worse and then she said I always cry and become angry when she speaks to me, that I have a very disgusting attitude. Pls was I wrong? 

I even started remembering all the things she has done to me while growing up, I am very scared of her and I can't help but tear up when she does things like this or when I talk about what she has done to me in the past. But apparently according to her my tears are a disgusting character I learnt somewhere
