It is 100% normal. My DS is going through the same experience. And depending upon whether you are naturally introverted or extroverted your experience is likely to be different than that of others you see on your dorm floor. As much as it may put you out of your comfort zone you should definitely try doing the things others have already suggested. But also know that once classes start it should become easier as you start seeing some of the same people on a regular basis. Good luck! I know this is hard and trust me it is really hard on the parents too who just want their kids to have a great college experience.
