Is it possible to see a therapist or mental health counselor without parents knowing?

I'm 18 and I really think that I have social anxiety and now it's getting in the way of my school because I'm too afraid to engage in any of the class discussion, even start to shake whenever i have to talk to more than 5 people and this is making my grades drop and now i'm at risk of being dropped out of college. I don't want my parents to know this. Can I see a therapist without my parents knowing? I mean, if I had to pay through insurance would my parents have to know?
