Talk to her show her do anything you can for her to really hear what your saying. My thing is were all humans we don't always understand each other even when we want to. Let her see your perspective. Always remember your parents are people just like everyone else including you. Only you know what you want from her so you need to figure out how to show her that. It's frustrating but don't be mad at her she's only human.
A mother wants to understand her children, you have to beable to talk to her not yell but talk.
Your mam was young once. Could you try and understand where she is coming from first ? Get her to talk about her childhood, her relationship to her mother. Might find you are more alike than you think. I will go out on a limb and say she wants the best for you. Start from there.
It works both ways. You can help her understand you better by trying to understand where she's coming from too. Communication is so important.
