As far as self-confidence goes, so much of social media is about approval, getting likes, comparing our lives to others' - meanwhile, confidence is an inside job: it's about how you feel about yourself regardless of what anyone else does or thinks. It's a knowing that you're human, you're flawed, and you're awesome in your own way.
You can be shattered, and then you can put yourself back together piece by piece. But what can happen over time is this: You wake up one day and realize that you have put yourself back together completely differently. That you are whole, finally, and strong - but you are now a different shape, a different size.
