Former Las Vegas resident and comedian Jimmy Kimmel has created a holiday to help you end superficial relationships online.
National Unfriend Day is Nov. 17 and a UNLV professor agrees with Kimmel.
Professor Natalie Pennington says that cutting toxic people out of your online life can help your mental health.
The professor also says it is a good idea to take time off from social media. A week or a month can help you reset.
