You seem to be getting way ahead of yourself. Until you can support yourself, you don't need to be getting into arguments with your mother about you moving out. Now, if the desire to move out and be independent serves as your inspiration to make it through school and find a job that will allow you to be your own person, then that makes tons of sense to me. My father was somewhat like your mother, and the desire to get out from under his roof motivated me to get myself independent.

Being independent of your parents is a normal, healthy goal for a person your age. It has two levels. One level is the actual physical independence of living separately. The other level is the psychological independence. That's when you get to where you do not need for your mom to agree with what you are planning in order for you to feel you have a right to your own plans.

When you are in the shower, can you not lock your phone, so your mom can't get into it? Can you not lock the bathroom door? Your mom doesn't respect appropriate boundaries. She will always be that way. So you have to use some strategy to maintain your boundaries. That includes what goes on in your head. It's your business, not hers. It's not for her to start thinking about what you should do when you get your bachelor's degree. Of course, a parent is going to have dreams. That's her right. She can pick what her dreams for you are. That's within her boundaries. Meanwhile, you come up with your own vision for your future and lay the groundwork to get there, and don't go advertising how your vision of your future differs from hers. That's just looking for conflict.

It's great that you are away at school. That's a terrific chance to have some freedom. Besides the physical independence that comes with having your own income and your own place to live, you need psychological independence. You have to recognize that you do not need your parents approval for everything. Yes, you need to abide the rules they set as a member of their household. But you are telling us that your mother made you stop talking to a friend? How is that possible when you are 18 years old?

You are wanting for you and your mom to be on the same page about too many things. That is psychological dependence. You are hoping for therapy to put the two of you more in harmony. That's a pipe dream. You think you need therapy because your aunt recommend it. Let your aunt and your mom have their ideas, and you come up with your own. Work toward making them reality. You'll get there. Meantime, avoid useless conflict.
