What can I do to prepare?

Okay so first off I graduated high school in 2014. I went to college for a semester but, unfortunately it didn't work out. I would go to class and participate and enjoy the learning but outside of class I wouldn't know what to do. Sometimes I would just sit in my dorm room and cry. So I ended up getting dismissed. Now it's August 2015 and I'm planning to enroll in a local community college for next fall then transfer after two semesters or so to a school with the program I want. The major would be fashion business, with a focus in e-commerce. I would love to do online marketing for a online clothing retailer.
