What is your background? Did you have friends in high school? How long have you been in university? Are you studying on campus? How do you know people are ignoring you? What country,or at least what general region?
Details matter. Provide whatever you feel comfortable providing.
Also, attending classes and circles are how you make friends. So if you are running away from the solution, expect the situation to stay the same.
Building community is important for most people, but it can be done at university, or elsewhere, or both.
