My mom keeps yelling at me?

I think you should try talking to your dad then. I mean you do appreciate his tones right? So why not ask your dad to help you figure out why she would yell at you all the time? Or maybe try your dad to convince your mom how she should use her indoor voice. That's what my dad does whenever my mom starts to yell at me for littlest things. I feel that you sound like a daughter who doesn't do anything bad and is being treated unfairly. Lastly trust me you are not the only one who's being scolded by their mothers because I've been there too.
