Hi there, I just graduated college and I've been there. you're a fresh person, not a lot of confidence, trying to fit in in a new environment it can be difficult and that affects your stutter. just take it easy, approach people, show interest, make some friends and it should improve hopefully. I was a terrible stutterer when I entered college but now I grduated this summer, got a job I feel more confident and I noticed I hardly stutter anymore and I'm doing things that seemed impossible 5 years ago like striking up conversations with relatives or randoms, actively going out... Hope it goes well for you and remember it's always going to get better from here on out <3
