financial situation

Okay hi! I applied for fall 2019 & I just wanted to vent and get some advice. I have gone to private school my whole life, but not payed for by my parents but rather my grandparents. I have a trust fund (only academic) from them. My parents are middle class. Growing up in a private school environment i’ve always felt the need to keep up etc, my parents always come through but no one really “knows” i’m middle class. My parents are middle/high class but by no means rich. Basically, my dad is telling me not to go to nyu or any of the other private schools I applied to because when the trust fund eventually runs out I will have to do student loans. What should I do? I feel like money shouldn’t be a issue if you get accepted to your dream school and it honestly makes me mad because my parents have it pretty easy with my rich grandparents giving me my education. What do you think? is it worth student loans? I don’t even know the full amount of my trust fun, I just want to make it big and I feel like NYU will help me get there
