Its becoming all to real

I just filled out my housing and first year seminar paperwork for college. I have spent 4 years in high school wondering who my room-mate would be in college, now I know his name is Aaron. I spent my whole school life wondering where I would be going, now I know it is University of Redlands. To be honest, I've spent my whole life wondering and pondering and observing, never once thinking of actually being there, but now that I am; that feeling of excitement is slowly being replaced, its actually a bit scary and daunting to know what lies ahead. There was a bit of safety in it not yet being a reality, still being a high school or middle school kid with more time to be at home. Now that I know exactly how much time I have left at home, it fills me with a ton of anxiety, its pretty weird. Believe me though, with all this said, I am super stoked to finally be going to college and to be able to enjoy what is coming, there is nothing like it, and I can't wait. I guess I'm just starting to understand the significance of all this too, and its pretty big.
