I have no clue either :(. I believe it's just a community college thing; I am going to one as well right now. I think it's just that CC doesn't have any real community in it, like at least my school has clubs, but no one goes to them.

When i first went to college i also was super scared of getting judged and having no friends to the point where i watched videos on how to make friends LMAO
so basically something that worked for me was to ask people their names and remember it so that they feel seen
In case you're way too scared to make the first step you can pass them a lil note and make a little doodle to give friendly vibes

Also at a community college and yeah I feel you it's hard to make friends at college. I have learned recently that I have no idea how to make friends lol. Ever friend I've had has approached me so now that I'm in college, most people head to either their next class or home/ work or where they are going. If they are in the student lobbies they (like me if I'm in one) are probably taking a short break in between classes or studying/getting work done. BUT the one advice is I guess during those in between class moments is probably the best time to talk to people.
