social media has impacted teens in a positive and negative way. Social media today makes teens feel like its a competition of who's better. For example nowadays teens are really insecure and have low self esteems. This is caused by social media, because when they see someone else who "looks better than them" they start to compare themselves to them which makes them feel some type of way about their physical appearance. But social media also impacts in a positive way, its a great place to make friends and express yourself. ( you dont have to say this : I guess it all really depends on if your the type to compare yourself to others or whatever )
hope this helped <3
