I find this relatable as someone who's somewhat introverted, but socially capable. For years, I denied that I had any form of social anxiety - but even in my late twenties when for better or for worse (maybe I'm letting myself go?) I've decided to stop care about being cool - the fear that I'll say something stupid or sound / look like a creep keeps me generally away from dining alone.

However, this was really only at places where mostly groups of friends / couples would dine. I've dated before, but sitting alone in a cool cozy place only seeing couples / friends having a good time just makes me feel like a robot.
