It has been called FOMO, or the fear of missing out.

Back in the day, people could just watch TV and get all of the information they needed for any given moment, but today, social media gives people many mediums to get information and find out what's going on at any time.

This creates a problem for some people, as this wealth of knowing of what others are doing all the time, can be overwhelming and can make them feel like they're missing out on something.

According to Dr. Travis Heath, a professor of psychology at Metropolitan State College of Denver, there isn't necessarily more going on in our lives today than before social media, we just have more ways of finding out what's going on in everyone else's.

"I don't think that we have more [things going on], necessarily, that we used to have, we just think we do because everyone's tweeting about it, posting Facebook status updates," Heath said. "Take online dating for example. That algorithm is endless.

There are so many potential partners. Before [social media and online dating], when we were dating, there was an endless supply of partners, we just didn't think about it. Now, we could be out on a great date, but could be wondering 'Is there something better? Is someone better looking at my profile?' and it creates this kind of fear of missing out."

Heath says that FOMO probably affects younger people more frequently because they use social media more, but older people get "sucked in" too.

"I think it stems from people sort of not engaging enough in their own lives," Heath said. "We're always kind of checking our phones, 'what is everyone else doing?' instead of really engaging in what is worth doing."

Heath says that, for people stuck in the pattern of FOMO, there are ways to try to get out of feeling left out.

He encourages people to find things that they are really interested in and engage in them.

"If we're doing that, we're fully immersed; we're not going to have a fear of missing out because we are doing something that is meaningful to us," Heath said.
