What did you post?
Summary:
"I say & do weird shit sometimes in order to hide the fact that I'm freaking the fuck out.
Please understand."
Also, just today I gave that same excuse of "Oh, I didn't get enough sleep last night. That's why I'm jittery." To the grocery store cashier today while I was writing a check. Which was a lie. I had plenty of sleep.

She even said to me, "Hey, are you okay? You can take your time with that check you know."
And I'm all: "Hahaha! Yeah, I'm fine! Hahaha!" *b-lines out the door*
