Emotional shutdown is similar. Our emotions are an indispensable part of our sensory apparatus and an essential part of who we are. They make life worthwhile, exciting, challenging, beautiful, and meaningful. When we flee our vulnerability, we lose our full capacity for feeling emotion. We may even become emotional amnesiacs, not remembering ever having felt truly elated or truly sad. A nagging void opens, and we experience it as alienation, as profound ennui, as the sense of deficient emptiness described earlier.
