The way I got over this kind of anxiety was to lead a study group in college. The people in the study group were already friends so it wasn't as stressing, but during the study group sessions, I made it my responsibility to lead the group. At first it was... unnerving, but definitely not as bad as it was with people I didn't know as well.

So maybe you should start with some friends that you're more comfortable with (not professional acquaintances) but in a different context than just hanging out?

I'm not sure if you've thought of this but you should apply to internships/co-ops while you're still an undergrad. If you have a summer break from school, a summer internship in Silicon Valley would give you the skills and experience that will make you appealing to future (post college) employers. Importantly, this will teach you how to work with others; I'm not sure how much experience you get with that from freelancing.
