This is a public service announcement.
I have impostor syndrome. The people I look up to have impostor syndrome. The people I'm friends with have impostor syndrome. People you look up to have impostor syndrome.
The most insidious thing about impostor syndrome is that it makes it mindblowingly unbelievable when you find out that your heroes have it as well--because why would they? They've made it, they're at the pinnacle, what excuse could they possibly have for thinking they don't belong, and it's nearly self-indulgent of them to have impostor syndrome.
But of course YOU have impostor syndrome. You've still got everyone convinced that you belong here. </sad trombone>
Just remember - impostor syndrome isn't about whether you belong. It's about whether you're ALONE with your impostor syndrome...and you're not. Hugs. Right there with you, buddy.
