Do you feel like you embarrassed yourself even though you didn't?

[Ghosty]

i'm the same as you! i constantly overthink and i'm always on my toes. "did i pronounce this word wrong?" "why am i moving my hands so much?" 

but i just remind myself that i'm probably overthinking it! by the end of the day, you would've been through so much, including your coworkers, that your "embarrassing" actions are probably not even on their mind at all! bonus points if they're preoccupied with something lately.

plus, like you said yourself, those embarrassing actions are probably not even embarassing in the first place!
