I believe it is OKAY if you don't have the answer to this. Not only is it intimidating to think about being all on your own and getting a real job to pay for bills and rent but it's all around a transitional period of your life from partying every weekend to getting more serious. Who wants to do that? Well it doesn't necessarily need to happen like that but it is a big difference than most of us are used to.
Embrace it, push yourself out into reality and don't be afraid to get hurt and screw up. Failure is going to happen in your life and if you can push passed it and deal with those issues to try again you will become even stronger. Don't ever be afraid to follow your dreams even if people say you are crazy, because anything can happen!
All I know is where ever I chose to go, I'm taking my pup with me.
