How to make friends?

I (19F) only really have one friend. We’ve been distant lately, but that’s life. How do I make friends if I don’t have many interests or hobbies? I’m afraid of putting myself out there, worrying that I’ll be judged or won’t fit in, so while being in college, I haven’t made any new friends. I’ve been told to join clubs or just say ‘hi’ to people in my class, but I get too anxious. What can I do from here?

This includes online friends, as my only friend was someone I met online. I’m afraid of being alone and am open to being friends with anyone! :,)
