Kevin Surace calls out joy killers: people, often old friends, who drain your energy and leave you feeling depleted. They're not bad people, but their presence is unhealthy. His advice: recognize when a relationship has become one and gently remove them from your life.

You at times do have joy killers in your life and you need to get them out of your life. We all have people that are friends. Maybe they were friends in high school or something, and here they're still friends, but they are a joy killer. And once I tell you that term, you'll know who we're talking about. And there's a point at which— and my wife uses this term, so I learned it from her— you have to bless them out of your life. These are good people. They're not bad people. But every time you're with them, they drain energy from you. So you can't be joyful about being with them because you fundamentally don't want to be with them. It's not that you're better or worse. It's just not healthy for you.
