Freshman Year

So today is my last day of my freshman year of college...Aren't I supposed to feel more grown-up? Isn't this supposed to be one of those days that I remember for the rest of my life? Why does it feel so unimportant and mundane? The only thing different is that I have that same fear in the pit of my stomach that I had when I was a senior in high school and I was graduating that night. It's this fear that I'm growing up too fast. I don't know how to make the fear go away and somehow it just keeps growing and growing. I guess maybe I am afraid that I will get old and then be disappointed in everything that I've done with my life.
