As a result of their complete dependence, infants become extraordinarily perceptive. Their only way to escape from intolerable terror is to develop perception skills. If an infant perceives that she is loved the way she needs to be loved by the huge all-powerful creatures around her, the anxiety that the creatures will not come when she needs them is alleviated.
But if she feels that she is not loved as she needs to be loved, the doubt of, “Will I be left here to die?” remains.
As the infant grows up, he becomes less dependent and more capable of caring for himself. But the foundational memory of being put at the risk of extinction by lack of love remains. And it’s not like the people who didn’t love the infant enough will suddenly feel overcome with love for him when he is five, fifteen, or thirty. So the constant reminders of the destructive lack of love are always present.
This wounded person will be so overcome by anxiety that he will try to regain control over the situation. The only way to do that is to convince himself that he caused the lack of love that threatened his existence. And if he caused it, he’s at least somewhat in control. (It’s the exact same mechanism as the one used by victims of crime, for instance.)
This is why he will cling to the belief that he’s not good enough. Because if he is good enough, then it must mean that this horrible experience of being unloved is not about him at all. All this suffering, and it’s not even about him! It’s much easier to convince himself that it is about him and he has provoked the lack of love by not being good enough.
So she will travel through life, seeking out proof that she is undeserving of love, fat, ugly, stupid, useless. Because if that is true, there is always hope that once she makes herself deserving, beautiful, thin, smart and successful, then the love will come. And if, God forbid, it turns out that she is already deserving, beautiful, thin, smart and successful, then that means the love is never coming. And that’s the hardest thing in the world to accept.
