Sighness infection 

A mood where you feel like sighing all the time. Usually the "infected" are unhappy, but may also be wistful or any other emotion which produces sighs. Not to be confused with clinical depression, which is more persistent but not necessarily more intense.

May also be called "sighnessitis."

Rubi contracts a sighness infection every time she thinks about how her sister Reema got into Harvard but she didn't.

Sitnession 

When somebody sits down as a sign of giving up or tiredness

Made by accident when a classmate of mine tried to spell something that I can’t remember.

It was too stressful for her so she sat down and did a sitnession
