Post-grad blues

I knew somewhere deep down I was sad about no longer being a student at UA, and I knew somewhere I was sad that things were changing. But the excitement of the next part of my life overshadowed that saddness. I was dreaming of having a master's degree and moving to a new city and feeling smart and successful. I was excited that my friends were moving on to new and impressive things. I was proud of them and their accomplishments and considered myself lucky to have such intelligent friends.
But all of a sudden, I don't like any of this at all. I don't want to go to to another school. I want to go back to undergrad at UA. I want my friends to go back to undergrad at UA. I want those days back, the days of meeting up in study hall, talking and complaining about class and trying not to laugh too loud at each other. The days of spending all day in Bryant-Denny Stadium screaming and jumping, cheering for the Tide, and meeting up afterward for pre-gaming and going out to the bars. Girls' Nights at Buffalo Wild Wings, meeting on campus for lunch in the Ferg. Just normal every day things will change, and I'm not ready for that change. Those years went by too fast. Looking back now I feel like I took them for granted. This time in our lives, the time when we'd all scatter to different cities, different school to start new things, was a million years away. It was only a distant dream. And thinking of it that way prevented me from preparing for it. I thought we'd be in college forever.
So now I've found myself at a very strange place in my life. I'm having trouble accepting this change and feeling ready to move on. I just spent a few days getting one of my very best friends set up in a new town. As I was driving home I realized I got to go back to the town she was missing, the town all those memories were made in, but the town wouldn't be the same anymore. She was one of the reasons it was home.
I also realized I'll be walking around a campus every day that isn't MY campus. It isn't covered with crimson and white and people getting excited about the game this weekend. And most importantly, my friends aren't there.
I know I have to accept these changes as part of life, and I need to learn to be excited about the next thing instead of just looking back and longing for old times. But I'm finding it to be much more difficult than I ever imagined.
