Interest bearing loan

I attend pharmacy school in the United States. It's my first year and as you might know I had to take out a loan because of the tuition. The tuition is extremely high so for the loan I had to take it out on a interest rate. I have taken out 2 loans so far both on interest. I am not doing well in my classes and I am on the verge of failing and getting kicked out. I have been fed up with this and I think it's because my tuition involves interest that's why. I want to leave but I do not know what I would after leaving this school and my parents don't understand; they want me stay here but inside I do not want to. What should I do? Please give me advice.
