Facebook Envy Is A Thing
For a long time following my joining Facebook, I believe I felt some of that Facebook envy. I'd see pictures of people's vacations in warm or exotic locations. I used to think 'wow, what a fantastic time and sure wish I could afford that.'
Several years ago, I stepped back and changed my outlook and became happy for them and started living vicariously through them. People were going to places I'd never been or may be able to get to and I started looking at it as 'man, what a wonderful place!' and thanking social media for making the world smaller.
It also helps to understand that what you see on social media isn't always 'real life' for that person.
