Yes I can make small talk for Britain, and am very gregarious at parties, but suffer from very bad social anxiety. I feel shy and worry that I look terrible, worry about everything I say, often tossing and turning thinking I've been a dick or offended someone, sounded stupid etc. I've talked to other people like me, it's kind of the reverse of the way introverts describe themselves, silence makes me uncomfortable, so I have to fill it. Doesn't mean I'm not feeling panicked about it.
