I really feel scared and lonely

I just moved out of my house, into my college dorm. I paid for my college and my dorm all by myself and didn't take any help from my parents. This morning i realised that I woke too late to have breakfast in the mess, i didn't have money with me. I asked my father for 5 dollars. He asked me very rudely "What's the purpose?. I felt so bad and humiliated. I never asked for anything. He is mad at me because I'm going to a college he doesn't like and I didn't become a doctor.

If i would be sick or in help, where will I go?. I don't understand what I did that makes him hate me so much. Maybe i deserve this.
