 If you have it, you're not alone. But I found this new app to be really fascinating. And if you are depressed or you know somebody who is, listen to this. There's an app called Rejoin, R-E-J-O-Y-N. It's the first FDA-approved app of its kind. It gives patients a six-week treatment program that trains them to have more control over their emotions. It targets the neuroplasticity, which is the brain's ability to form new connections and pathways.
