It's no secret that most people stick to posting positive things on Facebook, Twitter, and Instagram, and we don't need scientific research to prove the depressive effect that can have on us (though here are some anyway).
I'm guilty of being a part of this myself: I post smiling selfies and news about accomplishments, I don't usually take to Facebook to complain.
But truth be told, if you scratch below the surface you'll find there's a lot more going on than what you see through the lo-fi photo filter of digital life.
I post smiles because they make me happy during the difficult times. I choose to dwell on the good things in life as a cure-all. Glass half full and all that.
But on the other hand, there's absolutely nothing wrong with feeling sad. It's completely natural and everyone does sometimes... sometimes a lot... sometimes a lot more than they let off.
My point is, if you're feeling blue don't let the happiness of others get you down even more. We all have a lot more going on in our lives than you will ever see on a silly social network. Pull back the curtain and you'll find we're all on this same insane roller coaster called life.
