Guilt, anxious and fear

Recently I took admission in a tier 3 college CSE branch in Bangalore through COMEDK and seeing my father spending so much money on me is making me feel very guilty that I could have gotten better college if I studied hard and it would have been easier on his pocket but I tried i really did still couldn't get it and now here I am i know I can't keep weeping about the past and I should think how I can do the from what I have got and grind but still many thoughts are on my mind like I am very far away from home and I have no friends here though college hasn't started yet and the thought that being from North I will face discrimination or feel left out and the fear that what if again after working hand and doing everything I still couldn't get a job how will I face my parents who put so much money on me

Idk I just feel like a failure rn and I'm really anxious
