Being extroverted and having social anxiety - how is that even possible and how do i deal with it?

Yup this is my explosive combo! I love talking to my few close friends but I get really anxious about stuff that I probably shouldn't. I beat myself over things I said ages ago. I have near panic attacks when I mess up even a little in class but I still like to interact with people somewhat. It's all a big back and forth with that kind of mix. I really think that the only solution is to balance things out somehow but it seems pretty much impossible. Is there anyone out there that could relate or maybe throw a hint or two how to deal with that?
