feeling behind with making friends

hey! freshman here, and almost a month in and i still don't really have many solid friends yet. i am mostly around my roomates, who i get along with! but we don't click SO much to hangout with all the time. does it get better throughout the semester? any tips because it already feels like groups are formed and it feels so hard!!

i even attended a few club meetings, so far it's mostly been gbms so it's really huge. and it kinda felt like a lot of the people were returning members, so it felt a little out of place cause there were so many inside jokes being thrown around
