Making me take 4 classes

I wrote on here a week or so ago about my parents, Now they told me I have to go to school full-time to stay on their insurance.

I have been paying for my school for a year, I had to buy my own desktop computer (I wanted a laptop), I was told by my dad I didn’t need a laptop. I was 17 at the time. I now need a laptop. My parents are making me pay them back for my classes and books, I pay all my own bills, except utilities and food. My parents won’t accept any money those things.

I owe the $4225 for my car and transmission repair. Now I’m going to owe them $5100 by the end of the semester, my dad said I will have to take a cut in hours at work.

My Question is should I tell my parents that they have to pay for my school and let me work, or should I take a cut in hours and pay them back???

I have been working since 2005 when I turned 15, I have had very steady jobs. I worked really hard to get where I’m at hour wise. I do buy grocerys sometimes, I pay for my own gas, phone, credit cards, and clothes. I also pay for netflix for the family.

My sister got her 1st two cars paid for and my brother is getting his 1st car paid for, I’m the middle child. I will be 19 next week.

Help me please!!!
