Should I be this nervous about college?

Nope, colleges are built for people just like you. All of your needs and wants will be taken care of. You'll have staff to clean up after you. In high school you probably were treated like an inmate. In college you'll be treated like a customer. You'll have lots of friends and constant activities. You'll have all the privileges of being an adult and none of the responsibility.

When you graduate from college, then you should be nervous.
