Welcome to the forum. Thanks for sharing your story here.
I am sorry you feel confused and worried. You are trying to find your own way in life and feel your are getting no support from your parents only that they want to control you,
It is difficult when you have different ideas from your parents. Sometimes parents can seem controlling when they are worried about their children's future. The idea of a child leaving home and starting their own life and possibly making mistakes can seem very hard.
I was wondering if you have had career advice about the uni course you are thinking of doing. Is it uni your parents are worried about or just the course you have chosen?
You are trying hard to work out your future and I admire your determination.
