Tody I read that Facebook causes depression in teenagers. And no, not the serious medical condition. Like extreme sadness.
So, anyways, you're probably wondering, "How can Facebook make people depressed?" So I will explain.
A lot of times there are groups of friends who do everything together. But, sometimes, they do things without certain people, and post pictures of where they went to on Facebook. Then, those people who didn't get invited to go wherever the group went feel left out, and sad.
Also, people on Facebook try to make their life sound as happy as possible. They probably wouldn't share that their pet died. Here's a quote from where I read it: "You have a steady stream of people going to parties and having friends and showing off beautiful vacation spots. And there you are in your little life and your dog died. You know that your life isn't all parties and vacation spots. People do get depressed."
So, if you have a Facebook, be careful. And if your pet passes away, stay off of Facebook until you've recovered.
