There have been a multitude of these kinds of questions here over the past few weeks, so know that you’re not alone. The commonly given advice boils down to this:
- Get involved -- friends come from repeated exposure, whether in class or in clubs or in volunteering or whatever. It takes getting to know someone to be close, right?
- Give it time -- three weeks is probably less than 20% of the semester and a drop in the bucket of the two(?) years you have left. There is time, and making friends takes time.
