The butterflies won’t stop.

When you get butterflies in your stomach so much it makes you want to scratch them out so bad it hurts.

No matter how much you twitch and squirm they don't go away.

You try and try to catch them and put them in a jar but there's to many they just keep coming.

So in the end it's impossible to scratch them out so you deal with them and just wait for them do die.
