Your story is almost identical to what I've been going through. I transferred schools after my freshmen year and, although my new school is a MUCH better fit for me, I can't help but feel like I showed up to the party late. By that I mean that everyone already seems to have found their close friends. I don't drink or smoke and that definitely sets me apart from many of my peers. My best advice for you is to stay positive and reach out to the people you meet in class. My dad always tells me that people who do well in college don't necessarily go on to do well in life, and college is typically only four short years of a very long lifetime so it's more important to be able to succeed when you get out of school. Contrary to what most people think, college isn't the best time of every college student's life. I'm sorry I couldn't be more of a help to you but hang in there!
