Is it normal (added update)

So I’m 22, I live with my parents because I’m in college. I’m in state university and the only way to afford that is having my parents help me. (I can’t get grants or fafsa because of my parents income) today I was told by my dad I’m not allowed out of the house, and I’m only permitted to one day a month and that includes not being allowed to see my fiancé. As well as spending 40 hrs a week studying and in class I’m also supposed to spend another 40-45 hours at the family business. My fiancé works there and I was informed today that I’m no longer permitted to speak to any of my coworkers and I’m not allowed to listen to music, like the other coworkers do at work. And I’m also expected to raise my brother because my parents don’t have the energy to do it. I was also banned from going to the gym or running because my responsibilities are to my family and I’m in debt to them. I’m just asking if it’s wrong of me to feel like I’m being asked too much. And that I feel like I’m being controlled too much

Update:

As many are saying there is something “missing” I do not party (I never found interest in that) I don’t really drink or do drugs. I’m going to school to be a doctor, so I have to walk a straight line with the law and society. I don’t lie, and I live a pretty basic life. I’ve always tried to be respectful, but my parents believe that because they are spending money on me, I am an investment and therefore a financial risk. Their argument is driving anywhere or going anywhere puts me at risk of a car accident and if I get killed in one they are out the money they put into me. So that’s it.
