Heartbreak shares all the hallmarks of traditional loss and grief: insomnia, intrusive thoughts, immune system dysfunction. Forty percent of people experience clinically measurable depression. Heartbreak is a complex psychological injury. It impacts us in a multitude of ways. For example, Sharon was both very social and very active. She had dinners at the house every week. She and Miguel went on camping trips with other couples. Although Miguel was not religious, he accompanied Sharon to church every Sunday, where he was welcomed into the congregation. Miguel didn't just lose his girlfriend; he lost his entire social life, the supportive community of Sharon's church. He lost his identity as a couple. Now, Miguel recognized the breakup had left this huge void in his life, but what he failed to recognize is that it left far more than just one. And that is crucial, not just because it explains why heartbreak could be so devastating, but because it tells us how to heal. To fix your broken heart, you have to identify these voids in your life and fill them, and I mean all of them. The voids in your identity: you have to reestablish who you are and what your life is about. The voids in your social life, the missing activities, even the empty spaces on the wall where pictures used to hang. But none of that will do any good unless you prevent the mistakes that can set you back, the unnecessary searches for explanations, idealizing your ex instead of focusing on how they were wrong for you, indulging thoughts and behaviors that still give them a starring role in this next chapter of your life when they shouldn't be an extra.
