Johann Hari

Lonely people are scanning for threats because they unconsciously know that nobody is looking out for them, so no one will help them if they are hurt. This snowball effect, he learned, can be reversed—but to help a depressed or severely anxious person out of it, they need more love, and more reassurance, than they would have needed in the first place. The tragedy, John realized, is that many depressed and anxious people receive less love, as they become harder to be around. Indeed, they receive judgment, and criticism, and this accelerates their retreat from the world. They snowball into an ever colder place.
