need advice!

Hello, i hope you all are doing well! So im a 17yr old F, and my university is starting from Feb! The thing is that I've always been a introvert my whole life, my friends circle has always been small cause it takes time for me to get comfortable with someone, its not like that im scared of talking to new ppl, its just that I know it'll take time for me to make new friends there, and as i heard in a week or two ppl start making groups there, im scared what if i dont fit in:(
