When you are so overly excited about an upcoming event and you just can not wait ANY longer or else you'll "die", that you get actual anxiety from happiness.
"Oh, my, god, I can not wait for this movie to come out, why do we have to wait a month! I bet it will be amazing! Oh no, but what if I accidentally can't contain my eagerness any long that I go on a mad spoiler spree! I will ruin my experience! AHHH I can't do this anymore! I think I have Excitiety!
