You will be fine (and nobody else is as fine as they look!)
Try to find some activities that will bring you in contact with the same people on a regular basis, whether it’s volunteering, a hiking club, Intramural sports, an exercise class, a job on campus. You will feel less alone and get a low pressure way to get to know people. The counseling center often puts together groups of people to process their transition, which could help.
I know it feels lousy, but you are doing the right things. Hang in there.
