As a kid myself I know how moms and their children fight. It may seem like nothing at first, but then as the children grow up and you keep on fighting, then your relationship will break.
I’m only a teenager and I know what it’s like.
When I was little, me and my mom where best friends. And then as I grew up and she opened her own store she got more stressed and we where fighting more. She practically was screaming on everybody for no reason, kinda. And I am afraid that your relationship will break.
What you should do:
Try to stop and think what your mom is saying; she is always right. She is older then you and she knows better. Keep in mind that she loves you and would never hurt you. Help her around the house: wash dishes, clean, and make her breakfast in bed! This has always helped me. She starts saying what a good girl I am! It makes me so happy and it makes me happy that I know that she is happy.
