There are certain non-negotiables for introverts that their extroverted counterparts will just never understand.
Like a lizard on a sun-drenched rock, an extrovert gets a buzz from a chockers social calendar.
But an introvert? They need their time in the shade – lest they dry up like an over-socialised prune.
According to blogger Shawna Courter, there’s a name for the phenomenon.
She calls it the “introvert hangover” and explains it thus:
“Introverts have a more limited ration of energy available for socialising, compared to our more extroverted counterparts. When we push past those reserves, we hit a tipping point where we go from being ‘fine’ to ‘definitely not okay.’ An ‘introvert’ hangover is, simply put, a withdrawal into oneself brought on by overstimulation.”
For Shawna, at least, like its alcohol-fuelled equivalent, the “introvert hangover” is characterised by recognisable physical symptoms.
“Your ears might ring, your eyes start to blur, and you feel like you’re going to hyperventilate. Maybe your palms sweat,” she explains in a blog post for Introvert Dear.
“Your mind feels like it kind of shuts down, building barriers around itself as if you had been driving on a wide open road, and now you’re suddenly driving in a narrow tunnel. All you want is to be at home, alone, where it’s quiet.”
And if an introvert doesn't get their much-needed alone time? Well, basically they're stuffed, she says.
According to Shawna, that's when the self-doubt begins to kick in.
"Maybe I am no fun", you'll think as you're pummelled with a hangover induced waved of self-deprecation - only worsened by some well-meaning busy body asking: "Why are you so quiet?"
It's a cycle anyone who'd rather stay in their cocoon with a good book rather than emerge a social butterfly knows all too well - and one that's often misunderstood.
We asked around our office if the "introvert hangover" was real... All our resident introverts agreed it was.
Here's what they wished their friends could understand.
Making friends when being an introvert is hard. (Post continues after audio.)
1. Dinner on a school night is not an option.
A 6.30am start. Eight hours at a desk. Meetings. Ringing phones. Your Facebook pinging constantly.
The last thing most introverts want on a week night is dinner with friends, sorry.
