Facebook depression
A terrible mood caused by looking at Facebook and seeing how fake and perfect everyone else's life seems. It makes you feel like you're the only one failing at life.
You log on and see your ex posting vacation photos while you're still stuck in your parents' basement.
Your coworker posts about their kid's college acceptance while you're still trying to pass algebra.
Your uncle posts a picture of his new car, and you're still riding the bus.
