I’d say it’s just a matter of exposure and practice. If you force yourself to spend a lot of time in the kinds of situations that make you awkward, eventually you’ll figure out how to handle them, how to speak, how to react, what to say when etc. The more familiar it feels, the less self conscious and awkward you’ll feel.

And remember, people don’t care. People only think about themselves anyway, even if they notice your awkwardness they’ll forget it five minutes later so it doesn’t matter.
