Should I become a professional musician?

Alright. So im 18 years old and have been playing guitar for 6 years. Before that I played violin which I had been doing since I was 3 years old. Music is my pion and it has been for a long time, it is the reason I get up in the morning. All I ever think about is writing new songs and how I can incorporate interesting themes and ideas into my songs. I have a pretty experienced musical taste ranging in anything from Ravi Shankar to Kid Cudi but my favorite artist is Bob Dylan. I have been having this confidence issue though, mainly because I have never been in a (real) band. This is due to the lack of anything but metal musicians in my town(not to mention the fact that I am extremely introverted person), it just seems that no one has any interest in branching out from chugging and screaming. I have nothing against metal music it's just that I feel it is very frustrating to just limit myself to what everyone else has asked me to do. My big thing is experimenting. I had originally planned on going to Berkley School of Music but my parents didn't want to pay for any schooling that could lead to nothing in the future. Instead, now I am going to my parents alma mater and i'm not even sure college is for me anymore. I am quite adept at playing guitar, singing, and writing my own music but I have almost no performance experience. I also am not sure how to tell my parents that I don't really want to go to college anymore. I'm just so confused right now and I need some advice.
