Do people constantly ask you what's wrong?
It's probably because you suffer from resting b*tch face.
Many people suffer from this, including celebs like Kristen Stewart who always seems to look unhappy when she's actually not.
So is this just a face people put on, or is it actually a medical condition?
Science says it's actually the latter!
Research posted in The Washington Post says the people who have resting b*tch face actually have trouble expressing their emotions.
So you actually just can't help but show everyone how annoyed you are.
Behavioural researchers Jason Rogers and Abbe Macbeth analysed over 10,000 photos and were able to map out over 500 tiny signals that indicated the subject's emotions in the photo.
"One side of the lip pulled back slightly, the eyes squinting a little. It's kind of a tightening around the eyes, and a little bit of raising of the corners of the lips - but not into a smile."
They also studied a tonne of faces that were deemed expressionless. These faces were considered 97% neutral and only showed 3% of emotion.
The researchers even took a look at photos of celebs including Kristen Stewart who actually showed double the amount of emotions than the others, especially emotions of anger and disdain.
So, in a nutshell, those who have resting b*tch face just have trouble hiding their annoyance more than everyone else.
