This doesn't happen to most people, however. Keep in mind a few things as you begin to settle in to college life. If you have gone through life with only 1-2 friends that you've had since 7th grade, then there is a good chance you develop fewer and deeper friendships. If you had 50 friends in high school, then it is likely that it will just take you a few weeks to find people here with whom you feel comfortable.
Small actions can make a big impact.
The key is to relax, know that it is normal to start out feeling lonely. Some people will make good friends during the first month of college and then discover by winter break that they aren't really your type. You may find brand new friends by the end of J-term. That is okay. The benefits of that is that everyone seems to know everyone.
