Have you ever found yourself getting blue when you're on social media? It's almost impossible to scroll through your friends' posts about their brilliant children, gorgeous homes and new cars, and not come away wondering when your life hit the skids.
We've told you about similar studies done in the past about this subject, but now another study has confirmed what the others have found: Facebook could be making you miserable.
This time around it's a study from the University of British Columbia called "Why Following Friends Can Hurt You." It surveyed German university students and found that the emotion most associated with Facebook is envy, followed by lower self-worth and jealousy.
Most of the time, envy was triggered by posts showing leisure and travel, which also set off feelings of inadequacy 63% of the time.
These feeling are also more frequent in millennials, because other studies have shown that envy and jealousy decrease as you age.
So what should you do if Facebook has you down in the dumps? A different study from the Danish Happiness Research Institute found that people who quit, or took a break from Facebook, felt their lives improved 10%.
That's not to say Facebook is all doom and gloom. The study said 38% of respondents said they felt good while using the site.
