Of this, I am actually certain. After collecting thousands of stories, I'm willing to call this a fact: A deep sense of love and belonging is an irreducible need of all women, men, and children. We are biologically, cognitively, physically, and spiritually wired to love, to be loved, and to belong. When those needs are not met, we don't function as we were meant to. We break. We fall apart. We numb. We ache. We hurt others. We get sick.
