I was the same way at a very large campus. I dreaded anything that meant being around large groups of people. Going to the bookstore at the beginning of the semester was a huge fete for me. I would get so anxious and depressed listening to everyone socializing, laughing and I couldn't do that because my mind was so scattered and I was so disconnected to myself. You have to do whatever you can that is good for you. Your health is the most important thing. I have tons of memories about college every Fall and even have nightmares about it. I also have fantastic memories from Elementary School.
