My advice would be as follows:
1) Take a deep breath and relax. What you are going through is normal. Your whole life up to a few months ago has basically been spent working towards this ultimate goal of getting a college degree. It is normal to feel a bit of a let down coming off this achievement high.
2) Realize that developing an elite skill set is the key to finding exciting and meaningful work. For more on this check out this book: http://www.amazon.com/Good-They-Cant-Ignore-You/dp/145550912...
3) Get to work honing your craft.
