Dropping out of uni

Hello,I'm 20(F), I'm in my third year doing bsc.statistics,but guys I hate it since day one,I felt like I couldn't do any other thing,I didn't qualify for what I wanted which was medicine,I expressed this to my parents but they convinced me to stay,the cons also outweighed the pros,so I kept pushing,but yoh,I have been passing classes but getting the pass grade nun more ,I have no passion for it and have been busying myself with other things picked up hobbies.Recently, I have been very interested in films,poetry and writing in overall,that's really what I want to do,but I'm afraid of the rection I'll get from my parents that have invested resources and time into my studies.Somebody please tell me it's gonna get better.
