I'm not sure what I want in life.?

I'm a 16 year old girl. I have been playing violin since 3rd grade. I really don't enjoy it and I'm an average player. I have wanted to quit playing since 6th grade, but my mom never allowed me to. She says "This is what is going to pay for your college", and "Why quit when you've been playing for so long?". Now that college is getting closer and I still don't know what to do, I am starting to feel the pressure. All my friends know exactly what they want to do and I always hear my orchestra teacher talking about how excelent everyone in orchestra is and I feel left out. I don't know what I want to do when I get older. I'm terrifed of getting a part time job and I don't know why, I don't have a permit or license. I love learing about different cultures and different places in the world. I have said I would like to just travel the world, but how am I supposed to support myself if I just travel. I also love makeup and fashion, but I'm just a kid from the midwest who lives in the lower middle class area. I just don't know what to do.
