Don't be afraid to put yourself out there and continue trying new things that are a bit outside your comfort zone. Eventually you will find something that makes you happy, a real purpose.
Most people coming out of high school who seem to have a definite idea of what they want to do later realize they made that commitment too early. Take your time to find the things you value and start there.
I recently graduated college and it wasn't until my sophomore year that I realized I wanted to devote my time to the less fortunate rather than making big bucks as a pharmacist. I am sure you will grow as a person so don't worry yourself too much.
