College Expenses

I 18(f) have had to take out loans to pay for college. I know that’s common but my thing is my parents never told me they didn’t have anything saved up for my college and they pay for my sister‘s tuition so I assume they would pay for mine. I believe I go to a great school and because I didn’t know, I would have to shoulder the burden enough tuition alone this school is over 50 K a year. If my parents had told me that they weren’t going to help me pay for college I would’ve chosen in a cheaper school that gave me more scholarships. In the car a few days ago my dad was trying to guilt trip me saying I could’ve gone to college “for free”. However that’s not the case no school gave me a completely free ride, but there were school so they gave me more scholarship money and I didn’t consider them because they didn’t tell me that I would have to pay for college alone. Am I wrong for resenting them for not telling me?

P.S. Now that I know I’m paying for college by myself I am applying for scholarships and considering transferring to state school.
