I wish to draw attention to your comment about studying. I ask how old are you? School? College?

You do have some resources at hand. Whether high school or university/college there will be counseling services provided. In highschool this is usually a Guidance Counselor. If you are lucky, there may even be a Peer Support system. Even if it is only to vent, these services can help you - whether it be coaching you on how to broach the topic and have a conversation with your parents or referring you to additional help. In some cases, they can advocate for you on your behalf.

I am guessing you are at an age where your need for independence clashes with their 'last ditch' need to hang onto their child. This is diffult on both sides of the equation. As a parent, it was really hard for me to sit back and allow my children to make their own choices. It was all I could do to sometimes even refrain from catching them when they occasionally fell from making a mistake. Unfortunately not all parents feel able to have a hands off approach.

Again, if you feel unable to have 'that' conversation with them, seek out resources that might help or even coach you in doing so.

Regarding this studying thing, I suggest asking your parents what their expectations are on the matter. Inform them of your own needs and make sure you come to the conversation with a plan. I know such coversations went a lot easier in my household when my children did so. You may have to come to the middle ground.
