My father just yelled at me because he thinks I'm obsessed with music, art, and other cultures. I am so upset?

You should be studying a minimum of at least 2 hours per cl. Your GPA is not going to get you into medical school and even if it did I would not want a doctor who spent more time "playing" than studying. Even when you become a doctor you will not have time for all that because things change fast in the medical field and you will have to keep up with it by reading medical journals. Doctors do not have spare time. Maybe you should think about what you really want.
