How can i make friends in college when im a huge introvert?

I have no idea how to do this. I feel lucky enough that a there’s a girl who shares most of my classes that decided to go talk to me and hang out with me for a bit more than two weeks now. And she’s really nice but im obviously not the only person she’s friends with, and whenever she’s with other people i feel so uncomfortable, like im too much and i shouldn’t be here so i don’t even dare to speak except when it’s to reply. I don’t want to make things weird for her just because im too awkward to speak when her friends are here. Plus, besides liking anime, i don’t think we have that much in common. Im just really scared she’ll realize it and get bored of me.
And there are so many people i noticed that seem to like the same stuff as me, but im too scared to approach them everytime.
So i just feel so alone or that im a terrible friend, i don’t know how to fix my situation.
