Is it bad to want to just be rebellious?

Im 20 year female, and I just feel like I want to do everything I wanna do. It seem like I have just been living the way that my parents want me to live..that I don't even know myself and what I am capable of. A big decision that I want to make is joinin a sorority. My parents were not a part of the greek life, but my uncle was. My family doesn't know much about greek life, neither do I, but they say its dangerous and that is how people end up getting killed. It has made me once again feel like "Geeze, everything is negative and it makes me reconsider eventhough it is something that I want to do", and this is with alot of things that I want to do. And you want to listen to your parents but what about your decision? Does anyone have any advice? I just need help getting out this mold and becoming my own woman!
