I had a quarrel with my mother today, and then I got into a fight. My mother said that she didn't have my daughter and kept ignoring me. What should I do?

Mom's still angry! Give her some time. I believe that time can calm her inner grievances. But in the meantime, you still have to reflect on yourself! In any case, it is wrong to do it. That's violence! Because you are young and strong, you can beat an old man more than 20 years older than you. Isn't that "violence" Mom won't be reasonable. She's your mother, too. Raising you is the greatest favor to you, and you can't repay it all your life!
