New Beginnings Anxiety

I started college just last month and it's been so overwhelming! Every day feels like I'm learning a whole new world. Yesterday in class, the professor asked us to introduce ourselves, and my voice just cracked so bad that everyone could hear how nervous I was. I thought about skipping dinner but ended up going because I wanted to try out the vegetarian options they advertise online. Turns out, it's mostly just salads... Am I the only one who feels like this? Is it normal to be this anxious or am I doing something wrong? Any advice for dealing with all these new experiences would be amazing!
