What can I say to make my parents understand the way I am feeling?

Try asking them to do something specific to an active listening skill, like "can you tell me what you're hearing me say after I finish sharing?" It might help them actually listen and take in better what you're saying, and will help you feel heard more (even if they get it wrong, it helps to see them trying)!

Explain them every single thing you are experiencing right now. Sit down with them, take the time to let them sink everything in. Parents will listen to you, cause deep down they'll love you no matter what. You were born to be loved not hated

Before expecting to be understood, try to understand them as well. Understanding is best when mutual.

You have to think about their point of view. Assuming you know your parents relatively well, think about past talks you have had with them and what you did that made them respond understandingly - a certain way of phrasing something, for example. Try to think of their character and situation and put your feelings into words they can comprehend, while staying as close to the original meaning as possible.

You are a very capable person and you can find a way to show them. What if you try thinking of different scenarios on how to tell them. What does your heart say?

That should probably take more than one conversation with them. You can start by getting comfortable with telling them about you and how you spent your day for every day. Then follows, telling them your deep and personal thoughts.

Tell them to sit down, calmly, and talk this through. Nothing can be solved if there's no communication in it.

Parents, just like all people, are not psychic. I know it seems like they always have been. As a baby they knew when to change your diaper, when to feed you. As you grew up they knew how to cover your scratches and how to do your math homework. But now you are older and more of an adult. Answers no longer come out as easy as if you were a child. Now you have to communicate. It's one thing to have issues bubble up into an argument, but just like any other person telling the other what you think makes them know what you feel. You just have to understand that they may feel different about it.

Write down all your feeling from your perspective, take them out to eat/make them something, and have them read it

Make sure the atmosphere is calm. Words that are shouted are rarely listened to. Sit your parents down and explain to them calmly, in the best way that you can, and answer their questions.
